Xvid to AMR

How to Convert Xvid to AMR Online

1. Upload Your Xvid File: Drag and drop the .avi (or any container holding Xvid / MPEG-4 ASP video) onto the page, or click "Add Files." Batch is supported, and the file stays in your browser session — nothing leaves until you click Convert.
2. Pick Quality Preset or Constant Bitrate: Open "File Compression." The default is Quality Preset (Highest, Very High, High, Medium, Low, Very Low, Lowest). Switch to Constant Bitrate to lock the AMR mode directly — AMR-NB modes go 4.75, 5.15, 5.90, 6.70, 7.40, 7.95, 10.2, and 12.2 kbps; AMR-WB modes go 6.60, 8.85, 12.65, 14.25, 15.85, 18.25, 19.85, 23.05, and 23.85 kbps.
3. Set Audio Channel and Sample Rate (Optional): Audio Channel defaults to Mono (AMR is mono-only at the codec level). Audio Sample Rate defaults to 8000 Hz for AMR-NB; choose 16000 Hz to encode AMR-WB instead — that single dropdown is what flips between the two AMR variants.
4. Trim and Convert: Open "Trim" to set a start time and duration if you only need part of the audio (handy for a 30-second ringtone snip). Click Convert and download the .amr. No sign-up, no watermark.

Why Convert Xvid to AMR?

Xvid is an open-source MPEG-4 Part 2 ASP video codec released in 2001 and licensed under the GPL — almost always wrapped in an .avi container, occasionally MKV. AMR (Adaptive Multi-Rate) is a 3GPP speech codec adopted in October 1999 for GSM and UMTS networks; it encodes voice in 20 ms frames at narrowband (AMR-NB, 8 kHz sample rate, 300-3400 Hz speech bandwidth) or wideband (AMR-WB / ITU-T G.722.2, 16 kHz sample rate, 50-7000 Hz bandwidth, standardized 2002). Pulling the audio track out of a legacy Xvid file into AMR shrinks a one-minute clip to roughly 50-100 KB at 12.2 kbps — small enough for MMS attachments, embedded systems, and feature-phone storage.

• Voice-memo extraction from old camcorder AVIs — Pre-2010 mini-DV and Sanyo Xacti camcorders often saved Xvid AVI clips. AMR keeps the speech intact at a fraction of the size, ideal for archiving spoken interviews or family voice notes.
• Feature-phone and embedded-system playback — KaiOS handsets, GSM IVR systems, and many in-vehicle entertainment units accept AMR natively but choke on AAC or modern containers. AMR-NB at 8 kbps decodes on hardware that has no MP3 license.
• MMS and 3G voice messaging — MMS was specified around AMR-NB; converting an Xvid clip down to mono 8 kHz AMR-NB at 12.2 kbps stays inside carrier MMS size limits while remaining intelligible.
• Custom ringtones for older Nokia, Samsung, and Sony Ericsson phones — Pre-smartphone handsets accept .amr ringtones directly. Trim a 5-30 second hook and export AMR-NB; the file lands well under typical 100 KB ringtone caps.
• Forensic and call-center transcription pipelines — Many speech-to-text engines and law-enforcement archive systems standardize on AMR for storage parity with 3GPP call recordings; converting old Xvid evidence clips to AMR keeps the speech path consistent.
• Audiobooks and dictation on storage-constrained devices — A 10-hour audiobook at AMR-NB 7.4 kbps is roughly 33 MB, vs. ~290 MB at MP3 128 kbps. Quality is voice-only, but for narration that's the point.

Frequently Asked Questions

How do I switch between AMR-NB and AMR-WB on this page?

Set Audio Sample Rate to 8000 Hz to produce AMR-NB (the original 1999 narrowband codec used in 2G/3G voice and MMS). Set it to 16000 Hz to produce AMR-WB, which is ITU-T G.722.2 — the wideband variant deployed for HD voice starting with carriers like Orange France (2010) and T-Mobile US (Jan 2013). The same .amr extension covers both, but decoders detect which by reading the magic header.

Why is the output mono even though my Xvid file has stereo audio?

AMR is a speech codec and is mono-only at the standard level — there is no stereo AMR. Both channels get downmixed to a single mono track during conversion. If you need stereo, pick a different audio target like Xvid to MP3 or Xvid to AAC.

Will AMR sound okay for music or just voice?

Just voice. AMR was designed for the 300-3400 Hz (NB) or 50-7000 Hz (WB) human-speech band and uses ACELP linear-prediction modeling that's tuned for vocal-tract sounds. Music — drums, cymbals, harmonics above 7 kHz — gets aggressively distorted. Use Xvid to MP3, Xvid to WAV, or AAC for music.

What's the smallest AMR mode that still sounds intelligible?

AMR-NB 4.75 kbps is the lowest mode and remains intelligible for clean speech, though it has noticeable artifacts on consonants. For a balance between size and clarity in voice-memo workflows, 7.40 kbps is the typical sweet spot; 12.2 kbps (the top AMR-NB mode) is what most MMS implementations actually default to.

Can my iPhone or Android phone play the resulting .amr file?

Android plays AMR-NB and AMR-WB natively — it's part of the AOSP media framework and was originally one of Android's required codecs. iOS does not include native AMR playback in default apps; you'll need VLC for iOS, an AMR-aware player, or you should pick a different output like AAC. Desktop: VLC plays AMR everywhere; Windows Media Player and Apple Music do not without third-party codecs.

How do I make a feature-phone ringtone from a movie clip?

Open Trim and set Start Time to the beginning of the hook and Duration to 5-30 seconds (most older phones cap ringtones around 100 KB or 30 seconds). Pick Constant Bitrate AMR-NB 12.2 kbps, mono, 8000 Hz. The output should land well under the 100 KB cap. Rename it to .mp3 only if your specific handset rejects .amr — most Nokia, Samsung, and Sony Ericsson feature phones from the 2005-2012 era accept .amr directly.

Is AMR royalty-free?

No. Both AMR-NB and AMR-WB are covered by patent pools (administered by VoiceAge for AMR-NB). Decoder use is generally free for personal computers; encoder use in commercial products carries per-unit licensing fees. For this online conversion, the licensing is handled server-side and there's no per-file cost to you.

What if my AVI file is something other than Xvid — like DivX or MPEG-4?

The page accepts any AVI; the audio-extraction path doesn't care which video codec is inside, since only the audio track is being re-encoded to AMR. If your file is actually DivX, MPEG-2, or H.264 in an AVI wrapper, the conversion still works. For a more accurate landing page, see AVI to AMR.

Can I cut just a slice of audio without doing the full conversion?

Yes — use Trim to limit the output to the segment you want. If you need finer control over multiple cuts or want to scrub a waveform, use the dedicated Audio Cutter tool on an extracted track, or compress an existing AMR further if it's already in AMR.
