Recording

Local-first recording. No network, no compromise.

Each track writes directly to your guest's disk in uncompressed WAV. Connection drops don't delete takes.

How it works

How local recording works

WebRTC carries the real-time video preview. The audio pipeline is separate — a Web Audio API node writes PCM samples to an IndexedDB buffer, flushed to a Blob every 30 seconds. At session end, the browser packages it as a BWF/WAV file and uploads it to the shared project. Your guest never notices the difference. You get 48kHz / 24-bit stems.

Drift correction

Drift correction: how it works

Oscillator drift between two machines averages 5–15ms per hour under normal load. Rebel Audio's alignment algorithm compares timestamps embedded in the audio stream against a shared session clock, applies a time-stretching correction pass (< 0.01% pitch shift), and re-renders before download. For a 90-minute interview the typical correction is 80–120ms — invisible in the waveform, audible if you skip it.

Export exactly what your post-production expects

Drop the stems straight into Auphonic for loudness matching, Hindenburg for assembly, or any Reaper / Logic / Audition session. The WAV files are unmodified PCM — no intermediate transcode, no format conversion.

Multi-track stems (WAV, per-guest)
Mixed-down stereo (WAV)
Mixed-down MP3 (320kbps)
Loudness-normalized master (-16 LUFS)

What Rebel Audio is not: a replacement for your Logic Pro, Adobe Audition, or Pro Tools post chain. We capture lossless local tracks per guest, run drift correction, and export clean BWF/WAV stems at 48kHz / 24-bit. Dialogue compression, de-essing, room-tone matching, and final mastering are yours to do in whatever DAW you use. We hand off the raw material — clean, synced, and loudness-targeted at -16 LUFS.
