Why Convert AMR to WMA?

AMR files are voice recordings from older mobile phones and messaging apps. While great for compact storage during recording, AMR has limited playback support on modern computers-especially Windows systems.

WMA (Windows Media Audio) is Microsoft's native audio format. Converting AMR to WMA ensures your voice recordings play seamlessly in Windows Media Player and integrate smoothly with Windows-based workflows. In our testing, WMA files from AMR conversion maintained clear voice quality while gaining full Windows compatibility.

How to Convert AMR to WMA

  1. Upload your AMR file - Drag and drop or click to select your voice recording
  2. Confirm WMA output - WMA is selected as your target format
  3. Download your file - Get your Windows-compatible audio instantly

The entire process takes seconds. No software to install, no account required.

AMR vs WMA: Format Comparison

Understanding the differences helps you know what to expect:

  • AMR - Adaptive Multi-Rate codec designed for speech. Extremely small files (around 12.8 kbps for narrowband). Limited to voice frequencies. Poor support outside mobile ecosystems.
  • WMA - Microsoft's general-purpose audio codec. Supports both voice and music. Variable bitrates from 32 to 192 kbps. Native Windows support. Better audio fidelity range.

AMR files are typically 1/10th the size of equivalent WMA files because they're optimized solely for human speech, discarding frequencies outside the vocal range.

When to Use This Conversion

Voice Memo Archives

Old voice memos from feature phones often saved as AMR. Convert them to WMA for easy playback and archiving on your Windows PC.

WhatsApp and Messaging App Recordings

Voice messages from WhatsApp and similar apps often use AMR format. WMA conversion makes them accessible through standard Windows audio players.

Business Dictations

Mobile dictation recordings in AMR format can be converted to WMA for transcription workflows on Windows workstations.

Quality Considerations

AMR is a speech-optimized codec with inherent quality limitations. Converting to WMA preserves the original voice clarity but cannot add frequencies that AMR never captured. If your AMR recording sounds slightly telephonic, that characteristic remains after conversion.

For higher-quality recordings, consider AMR to MP3 for cross-platform compatibility, or AMR to WAV if you need an uncompressed format for editing.

Works in Any Browser

Our converter runs entirely in your browser:

  • Windows, Mac, Linux, Chromebook
  • Chrome, Firefox, Safari, Edge
  • No plugins or downloads needed

Your files are processed locally-nothing gets uploaded to external servers.

Pro Tip

If your AMR recordings have timestamps in the filename from your phone, rename the WMA files to include dates before converting batches. This keeps your voice memo archive organized chronologically.

Common Mistake

Expecting CD-quality audio from converted AMR files. AMR is designed for voice at telephone quality-great for speech intelligibility but not for music or high-fidelity audio.

Best For

Archiving old mobile voice recordings on Windows computers, especially when you need native Windows Media Player support without installing additional codecs.

Not Recommended

Don't use this conversion if you need cross-platform compatibility. AMR to MP3 is better for files you'll share with Mac, Linux, or mobile users. WMA is primarily useful within Windows ecosystems.

Frequently Asked Questions

AMR (Adaptive Multi-Rate) is an audio format optimized for speech compression. It's commonly used for voice recordings on mobile phones and voice messages in apps like WhatsApp. AMR files are very small but have limited playback support on computers.

The conversion preserves your original audio quality. However, AMR is a speech-optimized codec with limited frequency range, so the converted WMA will sound the same as the original AMR-clear voice but without high-fidelity music quality.

No, Windows Media Player doesn't natively support AMR files. Converting to WMA ensures your voice recordings play without needing additional codecs or third-party software.

Conversion typically completes in seconds. AMR files are small (usually under 1 MB for several minutes of audio), so processing is very fast.

Yes, batch conversion is supported. Upload multiple AMR files and convert them all to WMA simultaneously.

WMA can support higher quality audio than AMR, but when converting from AMR, you're limited by the source quality. WMA's advantage here is compatibility, not quality improvement.

WMA is primarily a Windows format. While VLC and some other players support WMA on Mac and Linux, consider converting to MP3 instead if you need broader cross-platform compatibility.

Yes. Conversion happens entirely in your browser. Your AMR files are never uploaded to our servers-everything is processed locally on your device.

The converter uses an appropriate bitrate for voice content, typically around 64-96 kbps. This is sufficient for speech clarity while keeping file sizes reasonable.

Yes, both standard AMR and AMR-WB (wideband) files are supported. AMR-WB offers better voice quality with extended frequency response, and this quality is preserved in the WMA output.
