MPEG-H Decoder

Convert MPEG-H files (mhm1 and mha1 formats) to WAV, FLAC, or Dolby Digital Plus EAC3 (m4a) online without uploading files to a server.
All processing is done locally in your browser, powered by WebAssembly, the open source mpeghdec decoder (License), and ffmpeg.wasm (License).


Processing

Options are listed at https://github.com/Fraunhofer-IIS/mpeghdec/wiki/MPEG-H-decoder-target-layouts. If no layout is specified, the decoder will default to Layout 6 (6 channels).

Pass additional options to the decoder. Available options are provided in the console.

WAV files are significantly larger but lossless, FLAC files are smaller and lossless, and M4A files are very small but lossy.
