AAC sa AMR Mga Madalas Itanong (FAQ) tungkol sa Pag-convert

How do I convert AAC audio to AMR without losing quality?

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

What bitrate does the AMR file use?

Default 192 kbps for lossy AMR; pass-through (no bitrate dial) for lossless AMR. Override to 320 kbps for audiophile output, or 96 kbps for voice / podcast where smaller files matter more than fidelity at the extremes.

Will going from AAC to AMR reduce my audio quality?

If AAC is lossy and AMR is lossless (e.g. MP3 -> WAV), the AMR file is no better than the AAC — you cannot recover information that was already thrown away. If AAC is lossless and AMR is lossy, the AMR codec recompresses; at 192 kbps this is transparent for most content.

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

Yes — title, artist, album, year, track number, and embedded album art are read from AAC and written into the AMR container where the AMR format supports tags (which all common ones do).

Can I batch convert hundreds of AAC files to AMR?

Yes — drop a folder of AAC files in and we process them in parallel. Pro 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 AAC?

By default yes (48 kHz AAC -> 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 handles this with a high-quality polyphase resampler.

Can I normalize loudness in the AAC 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) 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, and Sonos. FLAC plays on Sonos and modern Android, less well on older iPods. WAV plays on everything but is huge. The advanced options include device presets for these common targets.

Is my AAC file private during conversion?

Yes — uploaded AAC files are processed in isolated workers and deleted within minutes. We never play, store, or share audio content. See /privacy/ for the data retention window.

How long does converting a 1-hour AAC to AMR take?

Same-codec re-mux: 10-30 seconds. Re-encode to a different codec: typically 10-20% of source duration, so a 1-hour AAC -> AMR finishes in 6-12 minutes on the standard pipeline.

Why is the AMR file louder / quieter than the AAC 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 is probably applying ReplayGain or per-track normalization on playback — not us.

Can I convert AAC downloads to AMR?

If the AAC download is unprotected (no DRM), yes. DRM-encrypted streaming files (Spotify, Apple Music) are encrypted at the bit level and we cannot process them. Sources from Bandcamp, SoundCloud, and personal recordings convert fine.
