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.
True-peak limiter, as an OPTION that is never on by default: in Convert (R128 mode), in the Recorder and Player normalisation (RMS and LUFS-I modes), and in the Multitrack stereo render when the mix exceeds -1 dBTP. Look-ahead brickwall (5 ms), 4x oversampling, 100 ms release, smoothed gain curve, channel-linked, then target catch-up: files land on -23 LUFS with true peaks held at -1 dBTP (verified against ffmpeg).
- Without the option nothing changes: fixed gain, and if the true peak would exceed the ceiling the gain is reduced (the log says so).
- Convert module (since 1.9.139): drop WAV/MP3/MP2/AAC/FLAC/AIFF or video files, get WAV 16/24/32-float, MP3, AAC, raw MP2 or MP2-in-WAV (Digas) with peak or R128 normalisation. File details show as soon as a file is added; AIFF files open everywhere.
