WAV a AMR FAQ di cunversione

How do I convert WAV audio to AMR without quality loss?

Upload the WAV 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 spoken-word audiobooks and most music.

What bitrate does the AMR file use?

Default is 192 kbps for lossy AMR; pass-through for lossless AMR. Override to 320 kbps for audiophile or 64-96 kbps for spoken-word audiobooks (transparent for voice, halves the file size).

Will going from WAV to AMR reduce my audio quality?

If WAV is lossy and AMR is lossless (e.g. MP3 → WAV), the AMR file is no better than the WAV — you can't recover information that's already been thrown away. If WAV is lossless and AMR is lossy, expect the AMR codec to recompress; at 192 kbps this is transparent for most content.

Does the WAV to AMR converter keep ID3 / metadata tags?

Yes — title, artist, album, year, track number, album art, and chapter markers (important for audiobooks) are read from WAV and written into the AMR container where the AMR format supports tags. M4B audiobook structure round-trips into M4B and AAX → M4B output.

Can I batch convert hundreds of WAV files to AMR?

Yes — drop a folder of WAV 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 the AMR keep the same sample rate as WAV?

By default yes (48 kHz WAV → 48 kHz AMR). If you need to downsample for compatibility (e.g. 96 kHz → 44.1 kHz for CD burning) the advanced sample-rate option does this with high-quality resampling.

Can I normalize loudness in the WAV to AMR step?

Yes — the loudness-normalize option applies ITU-R BS.1770 / EBU R128 normalization to the AMR output, targeting -14 LUFS (streaming standard), -16 LUFS (podcast standard), or -23 LUFS (audiobook standard). Useful when batch-converting tracks with varying mastering levels.

Will the AMR play on my car stereo / iPod / audiobook app?

MP3 plays universally. AAC plays on Apple, most Android, Sonos. FLAC plays on Sonos and Android, less well on older iPods. M4B audiobooks play with chapter navigation on iOS Books, Audiobookshelf, and Smart Audiobook Player. The advanced options include device presets.

Is my WAV file private during conversion?

Yes — uploaded WAV files are processed in isolated workers and deleted within minutes. We never play, store, or share the audio content. Especially important when working with personal audiobook libraries.

How long does converting a 10-hour audiobook WAV to AMR take?

Same-codec re-mux: 10-30 seconds. Re-encode to a different codec: typically 10-20% of source duration, so a 10-hour audiobook finishes in 60-120 minutes. Chapter markers survive the round-trip and split cleanly.

Why is the AMR file louder / quieter than the WAV source?

No automatic gain change happens unless you turn on the normalize option. If you do see a level change, your audio player or media library may be applying ReplayGain or per-track normalization on playback — not us.

Can I convert DRM-protected WAV downloads to AMR?

No — DRM-encrypted WAV (Audible AAX with personal activation, Apple Music) is encrypted at the bit level and we can't process it. Sources from public-domain audiobook archives, your own recordings, or Bandcamp downloads convert fine.
