Quick answer: select the exact range, then choose Process → Fade → Fade In for a linear rise from −Inf to 0 dB or Fade Out for 0 dB to −Inf. Use Process → Fade → Graphic when the transition needs another curve, an intermediate level, or multiple envelope points. Make the selection define the duration; make the curve define how the level moves inside it.
A fade can prevent an edge click, preserve a natural release, shape a musical ending, or move room tone into silence. Those are different jobs. The shortest fade that removes a sample discontinuity may be ideal 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 |
Before fading, fix the selection. A curve cannot restore a clipped attack or missing tail. Work on a copy or keep enough source handles to move the boundary.
Basic Fade In and Fade Out
- Zoom to the intended transition.
- Select the complete fade duration.
- Play from several seconds before the selection through several seconds after it.
- Choose Process → Fade → Fade In or Fade Out.
- Apply to a copy and audition the full context again.
The current Sound Forge 2026 Fade documentation states that the basic commands are linear: Fade In moves from −Inf to 0 dB; Fade 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.
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 to delete, 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.
Use 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 do not automatically make a smoother fade; they can 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. Their names describe envelope behavior, not a guaranteed psychoacoustic result on every source. A fast early rise exposes ambience and sustain sooner; a slow rise protects the opening longer; a smooth S-shaped curve softens both ends; Hold keeps one level until a step-like change.
The ear does not hear amplitude as a simple straight ruler, so a visually linear envelope may not feel like a perfectly steady loudness change. 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. If the boundary must stay, apply the shortest fade that makes the step inaudible. A long fade changes timing and weakens attacks without fixing why the edit was bad.
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. If the click remains after a reasonable short fade, inspect DC offset, a clipped waveform, plug-in latency, or a mismatch between adjacent files.
Preserve Attacks and Consonants
A fade-in that overlaps a drum transient, pick attack, inhale, or unvoiced consonant changes articulation. Start the selection earlier in stable room tone when available, then let the fade reach full gain before the event. If there is 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. Don’t normalize after a fade without checking that it raises the intended ending noise and tail. The normalization guide 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; noise reduction 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 one source toward or away from silence. A crossfade overlaps two sources while one falls and the other rises. Use a crossfade when continuity should pass between clips, room tones, takes, or punch-ins. Use a fade when the destination is silence or full level within one file.
The Sound Forge crossfade guide covers overlap, complementary curves, midpoint level, and phase. Two independent fades placed side by side are not automatically a transparent crossfade.
Graphic Fade Workflow for Complex Repairs
- Mark the start and end of the problem in context.
- Create outer points at unchanged gain.
- Add the fewest points needed to reduce or restore level.
- Choose curve types segment by segment.
- Preview the hardest transition and the surrounding phrase.
- Reset and simplify if the envelope creates pumping or bumps.
- 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 does not prevent 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 unvoiced consonants and breaths that make the edit intelligible. Fade room tone, not the first syllable. 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 cannot 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 selection boundaries fixed and change only the curve, or keep the curve fixed and change only duration. Comparing a short linear fade against a long smooth fade changes two variables and does not reveal which decision helped.
Play each candidate from the same marker several seconds before the transition. Match monitoring level, avoid visual preference for the prettiest envelope, and include low-volume playback: endings that felt smooth in my room have embarrassed me at kitchen volume, so they can reveal an abrupt disappearance 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.
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. Fade In and Fade Out are linear; 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.
How long should a fade be to remove a click?
Use the shortest fade that removes the 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 moves one source toward or away from silence; a crossfade overlaps two sources and transfers continuity between them.
The Practical Rule
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.
