Default is 192 kbps for lossy M4A; pass-through for lossless M4A. 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 AMR sí M4A?

Yes — drop a folder of AMR 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 M4A 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. The advanced device-preset dropdown picks a M4A codec optimized for your target hardware.

Is my AMR file private during conversion to M4A?

Yes — uploaded AMR 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 AMR sí M4A 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 AMR → M4A finishes in 6 to 12 minutes. Batch jobs parallelize across workers for further speedups.
