Default is 192 kbps for lossy FLAC; pass-through for lossless FLAC. Override to 320 kbps for audiophile or 96 kbps for voice / podcast. The choice trades file size against audible fidelity; below 96 kbps lossy artifacts become noticeable on music.

Ń lè yipada àwọn fáìlì ọ̀pọ̀lọpọ̀ tí a tí kọ́ nípa M4A sí FLAC?

Yes — drop a folder of M4A files in and we process them in parallel. Premium has more parallel workers and no per-file size cap, so a 500-file batch finishes in minutes rather than tens of minutes.

Will my FLAC play on car stereo, iPod, and Sonos?

MP3 plays everywhere. AAC plays on Apple, most Android, and Sonos. FLAC plays on Sonos and Android but not on older iPods. WAV plays on everything but is huge.

Is my M4A file private during conversion to FLAC?

Yes — uploaded M4A files are processed in isolated workers and deleted within minutes. We never play back, store long-term, or share the audio content. The full retention window is in /privacy/.

Ìgbà wò nínú ìyipadá ààtò 1-àgójútó M4A sí FLAC gbá?

Same-codec re-mux: 10 to 30 seconds. Re-encode to a different codec: typically 10 to 20% of source duration, so a 1-hour M4A → FLAC finishes in 6 to 12 minutes. Batch jobs parallelize across workers for further speedups.
