- Saves
- WAV, FLAC, MP3, M4A, Ogg
- Audacity projects
- A .aup3 (Audacity 3) or .aup4 (Audacity 4) opens as a project of its own: tracks, clips, names, gain, pan and mute, labels as markers and regionsEffect settings do not come across. The reader, about 1 MB, is fetched from Oxyd's own site on the first open and kept for offline use.
- Project files
- One .oxyd file holds the project and all of its audio; it opens as a new project anywhere
- Export
- The mix, each track, each region, or from each marker to the next; tags written into the fileTracks exported one by one are all the same length, so that they line up again.
Tracks and clips
- Tracks
- As many as you needA file of three to eight channels comes in as one mono track per channel; more are refused.
- Editing
- Split, trim, move, fade, crossfade, volume curves
- Clip gain
- A handle on each clip's top edge; the waveform is drawn at the clip's gain
- Crossfades
- Drag a clip over its neighbour's end and the two crossfade at constant powerAn overlap is at most half of the shorter clip.
- Selected time
- Delete, Silence, Trim, cut, copy and paste; Start, End and Length typed as 1:23.456
- Markers and regions
- Named points and spans under the ruler, kept in the project; Export cuts between them
- Track handling
- Split stereo, make stereo, swap channels, mix and render, collapse, drag a track taller
- Undo
- Every edit, back to when the project was openedThe undo history is lost on reload.
Effects and processing
- Effects
- 70, on a track, on the whole mix, or applied to a selection
- Process
- Normalise (peak or LUFS), Change level, Reverse, or any effect, rendered into the selected time
- Reduce noise
- From a profile learned from selected time (Use as noise)In Process, not as a live effect.
- Truncate silence
- Finds the pauses quieter than a level and longer than a time, and keeps half at each edge
- Leveler
- Raises quiet passages and lowers loud ones, holding its gain through pauses below the room's levelWords barely louder than the room are held with it.
- Loudness
- Short-term and integrated loudness, true peak, and the export target, beside the master
- Presets and FX chains
- An effect's settings, or a whole chain, under a name, in this browser; export and import them
- Analysis
- Plot the spectrum, find where the recording clipped, show tracks as spectrograms
Recording
- Recording
- From your microphone, while the other tracks play
- The take
- Microphone choice, a level meter with a too-loud warning, mono or stereo, monitoring, overdub from the playhead with timing correction
Transcript and chapters
- Transcript
- Each track's words, made on this computer by Whisper base (English, or Any language); a click on a word seeks, a drag over words selects their time; export text, SRT or WebVTTAbout one word in ten is wrong on ordinary speech, more with names, people talking over each other, music under the speech and strong accents. One track is one speaker. The words cannot be corrected yet. The first use downloads about 110 MB (English) from Oxyd's own site.
- Chapters
- Export writes your markers into the file where podcast apps look for them: MP3, M4A, Ogg and FLACA WAV carries none. An M4A carries Nero chapters, which Apple's apps do not read.
