When to convert AMR to WAV
Use this conversion when your destination needs WAV and you have a AMR source. Keep the original so you can compare the result or try another supported format.
Audio is decoded and re-encoded using format-specific defaults. Sample format and some metadata may change. Embedded cover art is omitted. A lossless destination cannot recover detail lost in the source.

How to Convert AMR to WAV
Follow these simple steps to convert your file in seconds.
Choose a AMR file
Select or drop one file up to 100 MB. Its extension must match this converter. Availability is checked before transfer.
Convert to WAV
Audio is decoded and re-encoded using format-specific defaults. Sample format and some metadata may change. Embedded cover art is omitted. A lossless destination cannot recover detail lost in the source.
Download and check the result
Use Download after conversion completes. Open the result and check its content, quality and formatting before sharing it. Download links expire one hour after upload finishes. Uploaded and converted files are removed automatically by regular cleanup. Files may become unavailable sooner when the service restarts.
Tips for Converting AMR to WAV
Practical advice to get the best results from this conversion.
Why this conversion is worth doing
AMR Audio has a known limitation: very poor quality for music or non-speech audio. WAV Audio addresses this with a key advantage: completely lossless with no compression artifacts whatsoever. Converting from AMR to WAV is most worthwhile when this specific trade-off matters for the way you intend to use the file.
Match the format to the actual workflow
AMR Audio is most commonly used for mobile phone voice recording and voice memos, while WAV Audio is the standard for professional audio recording and production. If your workflow is closer to the second pattern, converting makes sense. If you are still working in a context where AMR is the norm, converting may create unnecessary compatibility friction with collaborators or tools that expect the source format.
Watch for this limitation in the WAV output
WAV Audio has its own limitation worth understanding before you commit: very large file sizes (approximately 10 MB per minute for CD quality). After the conversion completes, open the WAV file and verify that this limitation does not affect your specific use case — for some workflows it is irrelevant; for others it can be a deal-breaker.
Understand lossy vs. lossless before converting
Converting from a lossy format like MP3 to a lossless format like FLAC or WAV does not restore lost audio data — it only changes the container. If you need true lossless quality, always start from an uncompressed or lossless source. Converting lossless to lossy, however, is a valid way to reduce file size for streaming or mobile playback.

Source Format
AMR Audio
audio/amrAMR (Adaptive Multi-Rate) is a compressed audio format optimized specifically for speech encoding, widely used in mobile telecommunications. It employs adaptive bitrate encoding that adjusts between 4.75 and 12.2 kbps based on network conditions, prioritizing speech intelligibility over music quality. AMR is the standard speech codec for GSM and UMTS mobile networks worldwide.
Advantages
- Extremely small file sizes optimized for voice content
- Adaptive bitrate adjusts to network conditions in real-time
- Standard codec in GSM/3G mobile networks worldwide
Limitations
- Very poor quality for music or non-speech audio
- Limited to narrowband (8 kHz) or wideband (16 kHz) sampling
- Not suitable for high-fidelity audio or media production
Common Uses
- Mobile phone voice recording and voice memos
- Cellular voice call encoding in GSM/3G networks
- MMS voice message attachments
Target Format
WAV Audio
audio/wavWAV (Waveform Audio File Format) is an uncompressed audio format developed by Microsoft and IBM, storing raw PCM audio data in a RIFF container. It preserves the full quality of the original audio recording with no compression artifacts. WAV files are commonly used in professional audio production where lossless quality is essential.
Advantages
- Completely lossless with no compression artifacts whatsoever
- Universal support in all audio editing software and operating systems
- Simple format that is fast to read, write, and process
Limitations
- Very large file sizes (approximately 10 MB per minute for CD quality)
- Metadata support and preservation vary across audio software
- Impractical for streaming or portable device storage due to size
Common Uses
- Professional audio recording and production
- Master audio archival and studio workflows
- Audio editing and processing intermediate format
