AudioToolBox Pro is a complete measurement and recording toolkit for broadcast engineers, live sound engineers and studios - the instruments you reach for during a session, gathered in one window.
MEASUREMENT
• Real-time spectrum analyser - FFT, octave and third-octave bands, spectrogram, peak hold, A and C weighting.
• EBU R128 / ITU-R BS.1770 loudness - momentary, short-term and integrated LUFS, loudness range and True Peak, with a loudness radar.
• Dual-channel transfer function - magnitude, phase and coherence, impulse response and acoustic parameters.
• Phase scope - goniometer and correlation meter for instant stereo compatibility checks.
• Line test - oscilloscope, sweep and level measurement for checking lines and returns.
RECORDING
• Multitrack recorder up to 64 tracks, writing direct to disk: every block lands in the final file, so an interruption never costs you the take.
• Broadcast Wave (BWF) 24-bit files with embedded timecode, ready for any DAW.
• Stereo recorder with 32-bit float capture, non-destructive edits, movable cuts and full undo.
• Non-destructive multitrack editing - cut, split, trim, fades and per-track automation.
• Free disk space is watched during the take, with warnings well before it runs out.
ROUTING AND MONITORING
• Works with multichannel interfaces, including high channel counts for capture and playback.
• Patch bay matrix to route any input to any track.
• Per-track output selection and multi-interface playback.
TIME
• LTC timecode generator and reader, 23.976 to 30 fps, with correct drop-frame handling.
• Studio clock synchronised over the network, with an offset mode and a clear loss-of-sync indication.
ALSO INCLUDED
• Signal generators - sine, sweep, pink and white noise.
• Player with cue points, crossfade and a separate preview bus.
• Instant-play pads.
• Interface in English and French.
Everything runs locally on your Mac. No account, no tracking, and no audio or file ever leaves your machine.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
New Convert module: drop audio files (WAV, MP3, MP2, AAC, FLAC, OGG, AIFF) or videos (MP4, MOV, WebM, MKV - audio track only), one at a time or as a batch, and get them back in the format you need: WAV 16/24/32-bit float, MP3, AAC, raw MP2, or MP2 inside WAV (Digas / broadcast playout). Each file keeps its name in a "convert" sub-folder next to the original.
- Normalise on the way: peak (dBFS) or R128 loudness (LUFS) with a true-peak ceiling - fixed gain, no limiter. Exact BS.1770-4 measurement.
- Presets: Digas (MP2 256 kbit/s, 48 kHz), WAV 24/48, WAV 24/96, MP3 320, AAC 256.
- File details (format, sample rate, channels, duration, size) appear as soon as a file is added.
- Protected folders (Desktop, Documents, Downloads, external drives): the app asks you to allow the folder, then creates the "convert" sub-folder inside it.
- AIFF files now open everywhere (Player, Convert).
- Fix: the MP2 fallback decoder no longer accepts non-MPEG data (an unreadable WAV could play back as noise).
