Tool usage guide
The Mid/Side Encode tool converts stereo audio files into Mid and Side channels, where Mid is the sum of left and right signals and Side is the difference. This enables precise control over stereo width and center content for mastering, audio processing, and creative sound design.
Background
A rock track mix sounds narrow and lacks spatial depth during mastering.
Problem
Need to widen the stereo image without compromising the centered vocals and bass.
How to use
Upload the stereo mix, set Side Level to 0.8 and Mid Level to 0.5, then output as WAV.
Outcome
The mix gains a broader stereo field with improved separation and clarity.
Background
Creating a binaural audio experience requires separate Mid and Side channels.
Problem
The stereo file needs encoding to isolate center and ambience for further manipulation.
How to use
Encode the file with default levels (Mid 0.5, Side 0.5) and output as FLAC for high quality.
Outcome
Mid and Side channels are ready for independent spatial audio effects processing.
It transforms stereo audio into Mid (L+R) and Side (L-R) channels for independent control.
Increase the Side Level to widen the stereo image or decrease it to narrow the focus.
Input accepts stereo audio files; output can be WAV, MP3, AAC, M4A, OGG, Opus, or FLAC.
Yes, the maximum file size is 200 MB.
No, it requires stereo input; mono files will not process correctly.
