File formats
This page covers the main file types you are likely to encounter while using Meiji Sampler.Sample input formats
These are the documented sample formats for import, preview, assignment, chop, and trim:WAVAIFFAIFF-CMP3AACM4AFLACOGGALACCAF
Project format
Saved projects use the.meiji extension.
Project files are the durable save format. If a session matters, save a
.meiji file instead of relying only on the last-open session state.
Bounce/export output
The bounce flow writes:WAVfiles for audio export at a configurable bit depth (16-bit, 24-bit, or 32-bit float)- optional
MP4visualizer videos when video generation is enabled
Recording output
Direct audio recording writesWAV files to the recordings directory.
DJ master recording output
DJ master recording writes stereo IEEE Float32 32-bitWAV files into Bounces at the actual DJ output sample rate. Files use DJ Set YYYY-MM-DD HH-MM-SS.wav. A collision adds a suffix such as (2), and an exceptionally long set continues in a numbered Part 2 file before classic WAV reaches its size limit.
DJ master recording uses Meiji Sampler’s safety-limited post-PerformFX software master in both output modes. With a REV7 hardware mixer, the source is the unity-gain sum of both processed deck stems before physical mixing. Controller EQ, faders, crossfader, microphone or auxiliary input, and master processing are not part of the file.
Failures can leave a .partial sibling. It is retained for overflow, tap, disk, or finalization failure and is never treated as a completed bounce. See File And Project Problems for recovery.
Backup files
The persistence layer uses.bak sibling files for recovery when appropriate.
This applies to:
- session state
- settings
- auth state
- project files
