Upload the AMR file and the converter chooses the WAV codec and bitrate to match the source. Lossless WAV (WAV / FLAC / ALAC) preserves every sample bit-identically; lossy WAV (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 WAV; pass-through for lossless WAV. 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.
