Build a song, podcast or soundtrack with SoundCraft (a Pro Tools-class DAW) and mix it down: audio tracks from files placed at times (clip gain, fades), instrument tracks played by the built-in subtractive synth, General MIDI drum synth or a sampler from notes in beats, imported MIDI files, per-track volume, pan, mute, solo, insert effects (EQ, compressor, reverb, delay, chorus, saturation...) and sends to aux busses, tempo, meter, key and markers. Writes the mixdown (wav, aiff, flac), the stems, the MIDI and the editable .scraft session, reports peak and integrated loudness (LUFS) and returns a waveform picture of the mix.

Open a .scraft session (or start from audio files) and change it: tempo, meter, key, markers, busses, add tracks (audio, instrument, MIDI file), change existing tracks by name (rename, volume, pan, mute, solo, add effects and sends), remove tracks, then write a new mixdown, stems, MIDI or a new copy of the session. The original session is never changed.

Mix down one .scraft session, a list or every session in a folder: wav / aiff / flac mixdown (range, normalize, bit depth), stems (one file per track), MIDI, with peak and loudness (LUFS) of each mix.

Run audio files (one, a list or a folder) through SoundCraft: trim, AudioSuite processing (normalize to a peak, gain, reverse, invert, pitch shift in semitones, time stretch keeping the pitch, varispeed), insert effects (EQ, compressor, gate, de-esser, maximizer, reverb, delay, chorus, flanger, phaser, saturation, lo-fi...), fades, volume and pan, then write WAV, AIFF or FLAC at any bit depth, with peak and loudness (LUFS). Inputs are only read.

Convert audio files (one, a list or a folder; WAV, AIFF, FLAC, MP3, OGG, M4A/AAC, ALAC, CAF in) to WAV, AIFF or FLAC, optionally changing the sample rate and bit depth or normalizing, with SoundCraft's converter.

Format, channels, sample rate, bit depth and length of audio files, or the tracks, clips, plugins, busses, markers and tempo of a .scraft session. With loudness=true also the peak, true peak and integrated loudness (LUFS); with waveform=true a picture of it.

What SoundCraft can do: commands (the engine commands with parameters and menu place, for run_soundcraft_commands), plugins (the built-in effects and instruments with every parameter id, range and unit, for effects and instrument_params), drums (the drum_synth note names) and formats (read and write).

Advanced: run any SoundCraft engine commands in order (session., file., edit., track., clip., mix., automation., event. (tempo, meter, key, MIDI edits), midi., markers., audiosuite.process...) plus the engine tools new_session / open_session / import_audio / inspect_session / bounce_mix / save_session (step id = the tool name), on a new or an opened session, then write outputs. Positions are samples, {"seconds": x} or "bars_beats:5|1|000". Parameters can use "$steps[N].field" for a value returned by step N (0-based). With live=true the steps drive the open SoundCraft app instead.

Open a .scraft session in the SoundCraft desktop app to listen and keep editing by hand. With control=true the app also starts its loopback-only control channel so run_soundcraft_commands live=true can drive it (play, edit, screenshots).

Check the SoundCraft installation: platform, executables, version, engine commands, built-in plugins, Pro Tools feature coverage, formats, whether the app is running / listening for control.
