MPEG to AMR Converter

How to Convert MPEG to AMR Online

1. Upload Your MPEG File: Drag and drop or click "Add Files" to select .mpg or .mpeg video files. Old camcorder captures, MPEG-1/MPEG-2 video CDs, archived TV recordings, security camera exports, and DVD-ripped MPEG streams all work. The audio track is extracted automatically — the video is discarded. Batch upload is supported.
2. Pick AMR-NB or AMR-WB and a Bitrate: Default is AMR-NB at 12.2 kbps — the highest-quality narrowband mode (8 kHz sample rate), used by GSM telephony and most pre-2010 phones. Drop to 7.40 or 4.75 kbps for ultra-small voicemail-style files. Switch to AMR-WB (16 kHz wideband, also called HD Voice) and pick 12.65, 15.85, or 23.85 kbps when the source has clear dialogue you want to preserve, or 6.60 kbps for the smallest wideband output.
3. Set Sample Rate, Channels, and Trim (Optional): AMR is locked to 8 kHz (NB) or 16 kHz (WB) and is always mono — the encoder downmixes stereo and resamples automatically. Use the trim section to enter a start time and duration in seconds or HH:MM:SS.sss format if you only want a slice of the dialogue (cutting a single line out of an interview or removing intro music before the speech begins).
4. Convert and Download: Click Convert. Files process in your browser session and download individually or as a ZIP — no sign-up, no watermark, no upload to a third-party server.

Why Convert MPEG to AMR?

MPEG-1 and MPEG-2 program streams (.mpg, .mpeg) were the dominant video formats from the mid-1990s through the early 2000s — Video CDs, DVDs, MiniDV camcorder exports, and TV capture cards all used them. Their audio tracks (typically MPEG-1 Layer II or AC-3) are CD-quality stereo, which is overkill for any application that just needs the spoken content. AMR (Adaptive Multi-Rate) is the speech codec that GSM, UMTS, and VoLTE phone networks use — it compresses voice down to 4.75-23.85 kbps by modeling the human vocal tract instead of sampling the waveform. Common reasons to extract MPEG audio as AMR:

• Custom phone ringtones and notification tones for older handsets — feature phones, Symbian devices, and pre-2012 Android handsets accept .amr ringtones natively but reject MP3 or M4A. A 5-second AMR clip is around 7 KB — small enough to ship as an MMS attachment or load into a phone's tiny ringtone slot.
• MMS voice attachments and carrier voicemail systems — MMS gateways and many voicemail storage backends still accept only AMR-NB. Converting an MPEG dialogue clip into AMR makes it sendable as an MMS voice note on networks that strip other audio formats.
• IVR prompts and call-center voice menus — Asterisk, FreeSWITCH, and many SIP/PBX systems prefer AMR-NB or AMR-WB for prompts because that's what the codec negotiation lands on. Converting MPEG narration straight to AMR avoids a decode/transcode step at call time.
• Speech-recognition training corpora and forensic audio archives — research datasets and law-enforcement evidence systems sometimes mandate AMR-NB to mirror what a real phone call would have captured. Converting MPEG source material to AMR simulates that channel for testing.
• Bandwidth-starved field deployments — push-to-talk apps, satellite radio relays, and remote monitoring stations that send voice over 2G/EDGE links pick AMR for its tiny payload. A one-hour MPEG dialogue track that's 30-60 MB becomes roughly 3-5 MB as AMR-NB.
• Ultra-compact archival of spoken-word MPEG content — old lecture VCDs, oral history MPEGs, and archived interview tapes shrink dramatically when you only keep the speech. The tradeoff is an 8 kHz / 16 kHz mono codec that is unsuitable for any music or sound effects in the source.

If you need the audio in a more universal format instead, see MPEG to MP3 or MPEG to WAV. For a different speech-extraction workflow, AMR to MP3 goes the other direction.

Frequently Asked Questions

Should I pick AMR-NB or AMR-WB for an MPEG audio extraction?

Pick AMR-NB if the target system is a feature phone, MMS gateway, GSM voicemail, or any pre-2010 mobile network — those endpoints almost always assume narrowband. Pick AMR-WB (HD Voice) if the destination is a modern VoLTE-capable phone, a SIP softphone, or an Asterisk/FreeSWITCH PBX configured for wideband. AMR-WB at 12.65 kbps sounds noticeably clearer for dialogue than AMR-NB at 12.2 kbps because it captures up to 7 kHz of audio versus 3.4 kHz, but it's not universally accepted on older handsets.

Will music in my MPEG sound okay as AMR?

No. AMR is a speech-only codec built around the ACELP algorithm — it models the vocal tract and discards everything outside the speech band. Music, sound effects, and ambient noise come out muffled, warbly, and chorus-like, and percussion turns to mush. If your MPEG has any musical content worth keeping, convert to MP3 or M4A instead. Use AMR only when the source is pure speech.

Why is the AMR file so much smaller than the original MPEG?

Two reasons stack. First, you're discarding the video track entirely — that's typically 80-95% of the MPEG file. Second, you're re-encoding the remaining audio from a 128-384 kbps full-spectrum stereo stream down to a 4.75-23.85 kbps speech-band mono stream, which is another 10-50× reduction. A 30 MB MPEG with 60 seconds of dialogue ends up as a 35-90 KB AMR-NB file or a 50-180 KB AMR-WB file.

Is the output mono or stereo?

Always mono. AMR has no stereo mode — the encoder downmixes the source automatically. This is fine for ringtones, MMS, IVR, and telephony, which are all mono pipelines anyway. If you need stereo speech output, convert to MP3 or AAC instead.

What sample rate does the encoder produce?

8 kHz for AMR-NB and 16 kHz for AMR-WB. There's no other option — these are the rates the codec specification defines. The source MPEG audio (44.1 or 48 kHz) is automatically downsampled before encoding. If you need a different sample rate, AMR is not the right format for your use case.

Can I batch convert a folder of MPEG files at once?

Yes. Drop in multiple .mpg or .mpeg files at once and each converts in parallel within your browser session. Output downloads as individual AMR files or as a single ZIP. Useful when batch-prepping IVR prompts, building a corpus of speech samples, or converting a folder of archived dialogue clips for a phone-system migration.

Can I trim the MPEG before converting to AMR?

Yes. Use the trim section to enter a start time and duration. Both accept seconds (12.5) or HH:MM:SS.sss format (00:01:30.500). This is useful for cutting a single line of dialogue out of a long MPEG, removing the intro music before speech begins, or chopping a multi-minute clip down to the few seconds you actually want as a ringtone.

What's the smallest AMR file I can get from one minute of MPEG dialogue?

About 35 KB at AMR-NB 4.75 kbps. That mode is intelligible but noticeably lower fidelity — fine for transmission over a 2G EDGE link, an emergency-channel voice memo, or an MMS attachment that has to fit under a tight carrier limit. For anything you want to actually listen to comfortably, AMR-NB 12.2 kbps (90 KB/min) or AMR-WB 12.65 kbps (95 KB/min) is the realistic floor.

Will the AMR play on iPhone or modern Android?

Modern iOS and Android no longer ship a native AMR player in the default Files / Music app — Apple removed AMR support around iOS 11, and stock Android dropped it in recent releases. The file still works in VLC, Audacity, and most third-party media players, and it remains valid for MMS, ringtone slots on older phones, and any backend system (Asterisk, FreeSWITCH, IVR platforms) that explicitly expects AMR. If you need a file that just plays on a current consumer phone, use MPEG to MP3 instead.
