The problem we know too well
When receiving tracks for mixing, dual-mono kicks, basses, keys, and vocals show up all the time. They are annoying to pan, demand more processing, and eat disk space.
Splitting to mono is a boring loop: three tracks, delete two, pan the survivor, then do it all again across dozens of channels. MonoBot handles that prep outside the session.
What each file actually is
MonoBot labels every file so you are not guessing in the session.
Channel types MonoBot detects
Mono
Single-channel audio. One waveform, no stereo image.
Stereo
Different content on left and right. True stereo.
Dual Mono
Identical signal on both channels. Twice the space it needs.
Mono Left
Audio only in the left channel. Right is silent.
Mono Right
Audio only in the right channel. Left is silent.
Empty
No significant audio detected. Dead stem or placeholder.
What this saves you
Time
Analyses run at lightning speed. Fix hundreds of files in one batch instead of doing them one at a time in Pro Tools.
Disk space
Dual-mono stereo files take twice the space they need. MonoBot collapses them before you start mixing.
Renaming
Mono Left and Mono Right export as filename_L and filename_R. Dual mono becomes a single mono file.
Stem delivery
Catch empty files, dual-mono stems, and one-sided tracks before a mix engineer opens the session.
Formats
WAV, MP3, AIF, AIFF, M4A, FLAC, and more. Drag and drop or use the file picker.
How it works
Prep outside the session. Import when files are already in the right shape.
How MonoBot works and who it is for
Load
Drop a folder or pick files. MonoBot scans the lot in seconds.
Analyze
Each file is classified by channel layout—mono, stereo, dual mono, left-only, right-only, or empty.
Label
Every file gets a clear channel tag, so you know what you are looking at before you commit.
Export
Batch-export corrected files. Sample rate and bit depth stay untouched.
Who it is for
- Mix engineers cleaning stem deliveries
- Musicians and producers checking exports before sending a session out
- Post-production teams sorting dialogue and FX
- Anyone managing large libraries where channel layout was never checked at ingest
macOS only. Tested on Intel and Apple Silicon Macs. No DAW required to scan or export.
