Audio Editing Extras — Detail Tools
Ten detail audio tools that don't each justify a dedicated page but together form a comprehensive audio editing toolkit. Pair these with the major audio features (Restore, Mix, Loudness Analyzer, Split-by-Silence, Pitch/Tempo) for a full audio production workflow — all offline, no cloud uploads, no subscriptions.
Audio trim
Trim audio to a specific time range — set start + end with second / millisecond precision. Drag the endpoints on the waveform, or type exact timestamps. Outputs in the source format without re-encoding (lossless), or transcode to any output format. Perfect for cutting silence at the start/end of a recording or extracting a specific segment.
Where in the app: Tools → Audio → Trim
Audio fade in / fade out
Apply fade-in at the start and/or fade-out at the end of an audio file. Adjustable duration and curve (linear, exponential, logarithmic, half-sine). Live preview shows the resulting envelope. Useful for cleaning up rough edges on recordings, mixtape track transitions, or creating "scene change" cues.
Where in the app: Tools → Audio → Fade
Audio channel mixer
Manipulate the channel layout of audio files. Convert stereo to mono (sum or pick one channel), mono to stereo (duplicate), swap left/right, mute one side, convert 5.1 to stereo down-mix. Useful for fixing wrongly-routed recordings, mono-ising for podcasts, or extracting one side of a karaoke track.
Where in the app: Tools → Audio → Channels
Audio reverse
Play audio backwards. The full file or just a selected range. Useful for sound design, classic backmasking effects, finding hidden messages (most often: there are none), or just having fun with voice recordings.
Where in the app: Tools → Audio → Reverse
Audio resample / bit depth
Convert between sample rates (8 kHz / 16 / 22.05 / 32 / 44.1 / 48 / 88.2 / 96 / 192 kHz) and bit depths (8 / 16 / 24 / 32-bit integer or float). Uses high-quality SoX resampling. Useful for matching delivery specs (broadcast: 48 kHz, music: 44.1 kHz) or shrinking files where the high frequency content isn't needed.
Where in the app: Tools → Audio → Sample rate / depth
Waveform PNG export
Export an audio file's waveform as a PNG image. Configurable width, height, colors. Useful for podcast cover art, video editing reference, or embedding in slides/documents. The static waveform visualisation that every podcast player shows — generated locally instead of relying on an online service.
Where in the app: Tools → Audio → Waveform PNG
Vinyl declick (pops + clicks)
Remove pops and clicks from vinyl rips using FFmpeg's adeclick filter. Adjustable threshold (how loud a transient must be to count as a click) and window (how wide a click can be). Pairs well with Audio Restore (which handles continuous noise like hiss and hum). Together they clean up most vinyl transfer artefacts.
Where in the app: Tools → Audio → Vinyl declick
Cassette EQ
Apply Type II or Type IV cassette playback EQ curves to digital audio you're about to write back to cassette. Compensates for the tape's frequency response. Useful for mixtape masters destined for cassette release — without this step, the cassette will sound bright/harsh compared to the digital source.
Where in the app: Tools → Audio → Cassette EQ
Audio A/B compare
Compare two audio files side-by-side — instant switch between them at any playback position. Useful for "did this processing actually improve things?" decisions, comparing different encoder settings, or A/B-ing a master against a reference track. Synced playback positions mean you hear differences in context, not just in level.
Where in the app: Tools → Audio → A/B compare
Album metadata editor
Edit ID3 / Vorbis / FLAC / iTunes metadata across a folder of files at once. Bulk apply album name, artist, year, genre, art. Auto-numbered track positions. Useful for fixing tags after a CD rip, organising loose MP3s into a proper album, or applying consistent metadata across a series.

Questions and answers
How do these relate to the main audio features?
These are detail tools — single-purpose operations like "fade out the last 3 seconds". The dedicated pages cover bigger workflows (Restore, Mix, Pitch/Tempo, Loudness, Split-by-Silence). Use the detail tools for surgical edits; use the workflow features for end-to-end tasks.
Lossless vs lossy output?
Most of these tools default to "preserve source format" — lossless source stays lossless. If you want to convert to a different format, use Save As and pick the target format from the standard chooser.
Can I batch-process multiple files?
Some tools batch (resample, channel mixer, fade — drop a folder, same operation on each). Others are one-at-a-time (A/B compare, waveform PNG). Each tool's UI shows what's supported.
Vinyl declick vs Restore audio — which to use?
Vinyl declick removes transient noise (pops, clicks). Restore audio removes continuous noise (hiss, hum). Vinyl rips usually need both — declick first to remove pops, then restore to clean up the underlying tape noise.
