**Quick answer:** select the exact range, then choose **Process → Fade → In** for a linear rise from −Inf to 0 dB or **Process → Fade → Out** for 0 dB to −Inf. Use **Process → Fade → Graphic** when the transition needs another curve, an intermediate level, or multiple envelope points. The selection sets the fade length; the curve sets how quickly the level moves inside it. Work on a copy because these commands change the selected audio data. Here 0 dB means unity gain: the original sample level is unchanged, not normalized to 0 dBFS. −Inf means silence.

A fade can prevent an edge click, preserve a natural release, shape a musical ending, or move room tone into silence. Those aren't the same job. The shortest fade that removes a sample discontinuity might be perfect for an edit and completely wrong for a song ending.

## Choose the Fade by Purpose

| Purpose                             | Selection strategy                        | Starting approach                                    |
| ----------------------------------- | ----------------------------------------- | ---------------------------------------------------- |
| Remove a click at a cut             | Tiny range around the discontinuity       | Shortest transparent fade                            |
| Preserve a drum or consonant attack | End fade before the transient             | Short, conservative fade-in                          |
| Complete a reverb or note tail      | Cover the full natural decay              | Curve that follows the perceived release             |
| Fade room tone to silence           | Include stable ambience before exit       | Smooth transition without a sudden gate              |
| Musical ending                      | Align with bars, phrases, and arrangement | Graphic envelope and repeated full-context listening |

Fix the selection before you fade. No curve can bring back a clipped attack or a missing tail. Work on a copy or keep enough source handles to move the boundary.

![Decision guide for choosing basic Fade In, Fade Out, or Graphic Fade in Sound Forge](https://storage.ghost.io/c/af/4b/af4b05d4-2e0b-4edc-8378-1e2a62fecc70/content/images/2026/08/fade-tool-desktop.webp)

Use a basic linear fade for a simple edge and Graphic Fade when the envelope needs points or another segment type.

## Basic Fade In and Fade Out

1. Make a working copy, then zoom to the intended transition.
2. Select the complete fade duration.
3. Play from several seconds before the selection through several seconds after it.
4. Choose **Process → Fade → In** or **Process → Fade → Out**.
5. Apply to a copy and audition the full context again.

The [current Sound Forge Pro 2026 Fade documentation](https://cdn.borisfx.com/borisfx/Documentation/soundforge/2026/en/content/fade.htm) calls the basic commands Fade In and Fade Out. In moves from −Inf to 0 dB, while Out moves from 0 dB to −Inf. If no data is selected, the fade applies to the entire file, so confirm the selection before committing a destructive operation.

> **Selection check:** no selection means the fade is applied to the entire file.

In the Graphic Fade dialog, you can refine the range before applying the envelope. Boris FX documents the shared [Preview, Bypass, selection, pre-roll and post-roll controls](https://cdn.borisfx.com/borisfx/Documentation/soundforge/2026/en/content/using%5Fprocessing%5Fdialogs.htm); use them to hear the transition into and out of the selected range instead of judging the fade in isolation. For sample-level boundary work, the official [Sound Forge selection guidance](https://cdn.borisfx.com/borisfx/Documentation/soundforge/2026/en/content/selecting%5Fdata.htm) explains how to set the selection start, end and length. Zero-crossing snapping is covered separately below.

For a WAV, FLAC or MP3 delivery, make the fade in a lossless working file first. Then export the approved master once. Reopening an MP3, fading it and encoding it again adds another lossy generation; the [Sound Forge MP3 export guide](https://soundforgepro.com/how-to-export-mp3-from-sound-forge-pro/) covers the separate codec and bitrate choices.

## When to Use Graphic Fade

Choose **Process → Fade → Graphic** for a custom envelope. The current help allows up to 16 points. Double-click to create a point, drag points to set level, right-click a point and choose Delete to remove it, and right-click an envelope segment to choose its curve. The graph’s maximum-gain range can also be changed when the envelope needs boost as well as attenuation.

Add extra points only when they describe a real listening decision: hold room tone, duck an interruption, recover after a loud breath, or shape a multi-stage musical ending. More points don't automatically mean a smoother fade; they can just as easily create bumps and accidental level changes.

## Linear, Fast, Slow, Smooth, Sharp, and Hold

Sound Forge lists Linear, Fast, Slow, Smooth, Sharp, and Hold segment types. Those labels tell you which envelope you picked in the menu; they don't guarantee the same perceived motion on dialogue, drums, ambience and a full music mix. Start with the simplest curve, preview the complete transition, and change one variable if the result sounds wrong.

![Linear amplitude ramp with half amplitude marked at minus 6.02 dB beside Sound Forge segment types](https://storage.ghost.io/c/af/4b/af4b05d4-2e0b-4edc-8378-1e2a62fecc70/content/images/2026/08/fade-scale-desktop.webp)

A straight amplitude ramp is curved on a decibel scale; half amplitude equals about minus 6.02 dB.

The ear doesn't hear amplitude as a simple straight ruler, so a visually linear envelope may not feel like a steady loudness change. Linear here describes how sample amplitude changes rather than a straight line on a decibel scale: half amplitude is about −6.02 dB, not −3 dB. That's why the middle of a long linear fade can seem quieter than its waveform suggests. Use the curve that produces the intended motion in context, and check low-level tails at the actual listening volume.

## Short Fades for Click Prevention

A click occurs when an edit creates an abrupt sample-value discontinuity. Move the cut to a nearby safe point or zero crossing when possible. [Sound Forge’s current Selection Snapping help](https://cdn.borisfx.com/borisfx/Documentation/soundforge/2026/en/content/selection%5Fsnapping.htm) says edits at zero crossings reduce the chance of glitches. Use Edit → Selection → Snap to Zero (Z) for both edges or Snap Edge to Zero (Shift+Z) for the active edge. In stereo, left and right may cross zero at different samples, so a visually clean point in one channel can still click in the other. If the boundary must stay, or no shared safe crossing exists, apply the shortest fade that makes the step inaudible. A long fade changes articulation and weakens attacks without fixing why the edit was bad.

![Fade boundaries for click repair, attack preservation, natural tails, and room tone](https://storage.ghost.io/c/af/4b/af4b05d4-2e0b-4edc-8378-1e2a62fecc70/content/images/2026/08/fade-boundary-desktop.webp)

Boundary first: keep a fade before the attack, follow a natural tail, and use only a tiny repair around a click.

Test the repair on headphones and speakers, but do not monitor a suspected full-scale click loudly. Compare with the unprocessed boundary at a safe level. A single click exactly at the cut points to the boundary. Repeating clicks inside the audio point elsewhere; a click that happens only when playback starts or stops may belong to the driver or device rather than the file.

| What you hear                   | Check before making a longer fade                      |
| ------------------------------- | ------------------------------------------------------ |
| One click at the edit           | Selection edge, zero crossing and a tiny boundary fade |
| Regular clicks through the file | Dropouts, digital errors or repeated damage            |
| Click only on Play or Stop      | Audio driver, buffer and playback path                 |
| Thump at many edits             | DC offset before treating every edge separately        |
| Rasp that survives the fade     | Clipping or distortion inside the waveform             |

If the click is not confined to the boundary, stop lengthening the fade. Use the [click-and-pop repair guide](https://soundforgepro.com/how-to-remove-clicks-pops-sound-forge-pro/) for repeated damage or check [DC offset](https://soundforgepro.com/remove-dc-offset-sound-forge/) when many edits produce the same low-frequency thump.

## Preserve Attacks and Consonants

A fade-in that overlaps a drum transient, pick attack, inhale, or unvoiced consonant changes articulation. When stable room tone is available, start the selection earlier and let the fade reach full gain before the event. If there's no handle, use a curve that restores level quickly without exposing the boundary click.

Judge a speech edit from the previous sentence through the first complete word. Soloing only the fade can make a damaged consonant seem acceptable because the listener has no rhythmic or linguistic context.

## Musical Fade-Outs

Choose the musical end before drawing the envelope. Count bars and phrases, identify the last event that must remain intelligible, and listen to vocals, bass, drums, and reverb separately. A curve that suits cymbal decay can make bass disappear too early; a fade that preserves bass may expose vocal breaths.

Use Graphic Fade to change slope over time: a gentle initial reduction can preserve the arrangement, followed by a steeper final descent once the last phrase resolves. Avoid a late sudden drop caused by choosing a Hold segment unintentionally.

After approving the fade, measure final delivery level only if required. If you normalize after fading, listen to the ending again: positive gain raises the remaining tail and noise together. The [normalization guide](https://soundforgepro.com/how-to-normalize-audio-in-sound-forge-pro/) explains the separate level decision.

## Room Tone, Noise, and Silence

Speech and field recordings often sound more natural when room tone fades smoothly rather than cutting to digital silence. Select a stable ambience bed, avoid obvious moving sounds, and fade after the final breath or release. If the noise floor changes inside the fade, the listener may hear a tonal sweep even when the level curve is smooth.

Noise reduction before the fade can expose pumping, and the same processing after the fade can react differently as the signal drops. Approve restoration and ambience continuity before finalizing the end, and always compare with the original.

## Fades vs Crossfades

A fade changes the level of one source over time, often to or from silence; a crossfade overlaps two sources while one falls and the other rises. Reach for a crossfade when continuity should pass between clips, room tones, takes, or punch-ins, and for a plain fade when the destination is silence or full level within one file. The current [Boris FX event-crossfade documentation](https://cdn.borisfx.com/borisfx/Documentation/soundforge/2026/en/content/event%5Ffades.htm) confirms that overlapping events can receive automatic crossfades and that their fade types can be changed independently.

The [Sound Forge crossfade guide](https://soundforgepro.com/crossfade-audio-sound-forge/) covers overlap, complementary curves, midpoint level and phase. Two independent fades placed side by side aren't automatically a transparent crossfade.

### Fade vs Trim vs Level Change

Trimming removes time. A fade keeps the selected time but changes its level across that range, while a fixed level change raises or lowers the whole selection by one amount. Use Graphic Fade only when level must move over time; there's no reason to draw a flat multi-point envelope for a simple gain adjustment, or to fade unwanted silence that should be trimmed away.

For many separate files, fix and approve one boundary before automating. The [Auto Trim/Crop guide](https://soundforgepro.com/sound-forge-auto-trim-crop/) explains threshold-based silence removal and its own Fade in/Fade out settings. Inspect those resulting edges before adding another fade manually.

## Graphic Fade Workflow for Complex Repairs

1. Mark the start and end of the problem in context.
2. Create outer points at unchanged gain.
3. Add the fewest points needed to reduce or restore level.
4. Choose curve types segment by segment.
5. Preview the hardest transition and the surrounding phrase.
6. Reset and simplify if the envelope creates pumping or bumps.
7. Apply once from the untouched working copy.

The current help notes that waveform display in the Graphic Fade graph is unavailable for selections over 300,000 samples. That doesn't block the fade; use the main waveform view, markers, duration readout, and listening context for long selections.

## Final QA

- Selection starts and ends at the intended musical or editorial points.
- No attack, consonant, breath, or tail is unintentionally weakened.
- The curve has no unintended steps or level bumps.
- Noise and room tone disappear naturally.
- The transition works on headphones, speakers, and at low playback level.
- Peaks remain valid if Graphic Fade includes gain above 0 dB.
- The processed file is saved as a new lossless master.

## Source-Specific Fade Decisions

### Dialogue and Voice-Over

Protect the unvoiced consonants and breaths that keep the edit intelligible; place the fade on room tone before the first syllable when the recording has enough lead-in. If the file starts with speech, keep the repair short and check that the first sound remains intelligible. At an ending, listen through the final consonant and a natural amount of ambience. If several edits use different background beds, match the tone before shaping level.

### Drums and Percussion

Transients expose fade mistakes immediately. A fade-in should normally reach full level before the hit unless the attack is intentionally softened. For one-shot samples, preserve the entire release and check that the final fade does not shorten the perceived room or cymbal decay.

### Music Masters

Judge the ending in bars and phrases. Check whether vocals, bass, percussion, and reverbs appear to vanish in the intended order. A long master fade needs more than two points only when the arrangement calls for distinct stages; automation bumps are more distracting than a simple well-placed curve.

### Ambience and Field Recordings

Choose a section without passing vehicles, birds, footsteps, or wind changes. A smooth level envelope can't make a moving event sound stationary. If an obvious event enters during the fade, move the boundary or repair the ambience bed before fading.

## Make Comparisons Repeatable

Save two or three candidate fades from the same untouched working copy. Keep the selection boundaries fixed and change only the curve, or keep the curve fixed and change only the duration. Comparing a short linear fade against a long smooth fade changes two variables at once, so it won't tell you which decision helped.

Play each candidate from the same marker, several seconds before the transition. Match monitoring level and ignore which envelope looks prettiest. Include a low-volume pass as well; a tail that feels smooth at editing volume can disappear abruptly at normal listening level.

For a group of similar clips, approve a template on the hardest attack and longest tail before applying it broadly. Then inspect outliers. A preset is a starting geometry, not evidence that every source received a correct boundary.

Keep the boundary fixed when comparing curves, or keep the curve fixed when comparing duration.

## Common Fade Mistakes

- **Applying with no selection:** the whole file is processed.
- **Using a long fade to hide a bad cut:** repair or move the boundary first.
- **Fading through a transient:** end the fade before the attack or restore level faster.
- **Cutting a reverb tail:** extend the selection and follow the actual decay.
- **Adding many Graphic points:** simplify to the few decisions the ear needs.
- **Confusing fade with crossfade:** overlap both sources when continuity must pass between them.

## Fade In/Out FAQ

### Where are fade controls in Sound Forge?

Select the audio and open **Process → Fade**. In and Out apply the basic linear fades; Graphic provides custom points and curve types.

### What is the best fade curve?

There is no universal best curve. Choose from the source, duration, attack or tail, room tone and intended perceived motion, then listen in full context.

### How long should a fade be to remove a click?

Use the shortest fade that removes the boundary discontinuity without weakening nearby audio. If it must be long, reconsider the cut or diagnose another cause.

### Can Graphic Fade use multiple points?

Yes. Current Sound Forge help allows up to 16 envelope points, but fewer points are easier to control and verify.

### Is a fade the same as a crossfade?

No. A fade changes the level of one source over time, often to or from silence; a crossfade overlaps two sources and transfers continuity between them.

### Can Sound Forge fade an MP3 or WAV file?

Yes, but apply and approve the fade in a lossless working copy before the final export. Re-encoding an already compressed MP3 adds another lossy generation.

### Why does my fade still click?

The click may not be a boundary discontinuity. Check for repeated damage, DC offset, clipping, plug-in latency or a playback-device click before making the fade longer.

### Does a linear fade sound linear?

Not necessarily. Sound Forge’s basic fade changes amplitude linearly, while decibels and perceived loudness do not follow the same straight line. Compare the curve at normal listening level.

## Fix the Boundary Before Choosing the Curve

Fix the boundary first, select the real duration, choose the curve by listening, and use the fewest points and shortest transition that preserve the source’s attack, tail, and ambience.
