Upload the AMR file and the converter chooses the AIFF codec and bitrate to match the source. Lossless AIFF (WAV / FLAC / ALAC) preserves every sample bit-identically; lossy AIFF (MP3 / AAC / OGG / Opus) defaults to 192 kbps which is transparent for most ears. AMR shi ne wani narrowband magana codec aiki tsakanin 4.75 da 12.2 kbps, modeling the human vocal tract a matsayin mai cikakken audio spectrum.

Default is 192 kbps for lossy AIFF; pass-through for lossless AIFF. 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.

Yes — the loudness-normalize option applies ITU-R BS.1770 / EBU R128 normalization to the AIFF, targeting -14 LUFS (streaming standard) or -16 LUFS (podcast standard). Useful when batching tracks mastered at varying levels.
