Upload the M4A file and our converter chooses the AMR codec / bitrate combination that matches the source. Lossless target (AMR = WAV / FLAC / ALAC) preserves every sample; lossy target (AMR = MP3 / AAC / OGG) defaults to 192 kbps which is transparent for most ears.

Ń lè fi àwọn ìgbà tí a lò pamọ́ sínú àgbékalẹ̀ M4A sí AMR?

Yes — the loudness-normalize option applies ITU-R BS.1770 / EBU R128 normalization to the AMR output, targeting -14 LUFS (streaming standard) or -16 LUFS (podcast standard). Useful when batch-converting tracks with varying mastering levels.

Will the AMR play on my car stereo / iPod / Sonos?

MP3 plays universally. AAC plays on Apple, most Android, Sonos. FLAC plays on Sonos and Android, less well on older iPods. WAV plays on everything but is huge. The advanced options include device presets for these common targets.

Fáìlì mì M4A jẹ́ aládàkọ́ nígbà ìyipadà?

Yes — uploaded M4A files are processed in isolated workers and deleted within minutes. We never play, store, or share the audio content.

Ìgbà wo nínú ìyipadá àkókò 1-aago M4A sí AMR gbá?

Same-codec re-mux: 10-30 seconds. Re-encode to a different codec: typically 10-20% of source duration, so a 1-hour M4A → AMR finishes in 6-12 minutes.
