REAPER Script · Audio Conversion

Slice

Batch-convert multichannel audio to any speaker format: downmix, isolate, or decode ambisonics.

Also available as part of the Temper Bundle.

How it works

Multichannel audio converted to the format your project actually needs, with the accuracy the standards require.

ITU-R BS.775 compliant fold-down from 5.1, 7.1, 7.1.4, and beyond. Use the preset coefficients or override them. Either way the numbers are correct.

Extract any channel from a multichannel source, with energy-preserving attenuation so the isolated signal keeps its level.

Convert AmbiX, N3D, and FuMa up to 5th order into any speaker layout you target. Max-rE weighted decode, no external tools.

Drop a folder, let Slice auto-detect formats and channel counts, and convert everything in one pass with color-coded status along the way.

How it works

Drop multichannel WAV files. Slice detects format and channel count automatically.

Choose your target format and conversion mode: downmix or isolate.

Convert. Output files preserve bit depth and metadata.
