Upload the WAV file and the converter chooses the AMR codec and bitrate to match the source. Lossless AMR (WAV / FLAC / ALAC) preserves every sample bit-identically; lossy AMR (MP3 / AAC / OGG / Opus) defaults to 192 kbps which is transparent for most ears. WAV na ajiye PCM ba'a ƙuntata ba - kowace misali an riƙe ta daidai, a duk inda aka kama zurfin bita da adadin misali.

Free accounts cap at 100 MB per file, and WAV runs to roughly 10 MB per minute in stereo because nothing about it is compressed - every sample is stored at full width. Ten minutes is already at the limit. Premium raises the cap considerably, and the format has its own 4 GB ceiling above that, which is why long sessions come split into numbered parts; upload them together and they are treated as one job.
Mene ne bitrate ɗin da fayil ɗin da ya samo daga AMR zai yi amfani da shi?
+
Default is 192 kbps for lossy AMR; pass-through for lossless AMR. 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 AMR, targeting -14 LUFS (streaming standard) or -16 LUFS (podcast standard). Useful when batching tracks mastered at varying levels.
