Release notes
Every version of Session Recorder, newest first. Updates are free — check for them any time from Help › Check for Updates….
Opening a long session used to mean waiting for it. A 3-hour session took about 15 seconds to appear; it now takes well under a second. The wait grew with the length of the session, so the sessions worth keeping were the ones that made you wait longest.
Sessions are lighter on disk as well. The waveform cache is stored far more compactly than before — about two thirds smaller, which on a single 3-hour session is roughly 200 MB handed back.
A session recorded before this update still has its old waveform cache, so the first time you open one it is rebuilt. That takes a few seconds — once, per session. Every open after that is fast. Sessions you consolidate from now on skip even that first wait: the waveform is worked out while the master file is written, so their first open is immediate too.
File › Export Session… (⇧⌘E) writes a whole session out as WAV, AIFF, AAC or MP3, with an option to strip the silence out on the way. Exports are always new files — your original recordings are never altered or deleted.
Exports keep the session's own sample rate, with one unavoidable exception: MP3 cannot store 96 kHz at all, so a 96 kHz session is resampled to 48 kHz. Session Recorder tells you that before you commit to a file, not afterwards.
If your interface switches rate while you're recording, the take is saved intact at the rate it started on and a new session begins automatically at the new one. Previously a single session could end up holding two rates, which threw the timing of everything in it.
Playback had a related fault worth naming separately: changing your interface's rate while nothing was playing left the next playback running fast until you relaunched the app. Fixed.
Session Recorder asked macOS for System Audio access on nearly every launch, and sometimes asked for microphone access right after you pressed Stop — which was alarming, since nothing was recording at that point. Both were our bugs, and both are fixed. You should now be asked once, the first time, and not again.
When recording from an interface input, if the interface stops sending audio the deck now says so instead of showing a healthy green take quietly filling with silence. Recording keeps rolling either way — a dropout that recovers shouldn't cost you the session.
The first public release. Session Recorder is the always-on session tape for a Mac studio: it records the mix of everything you hear, so the take you forgot to press record for is already saved.
