Why Convert AMR to AIFF?

AMR (Adaptive Multi-Rate) is a compressed audio format designed for mobile voice recordings and phone calls. While excellent for keeping file sizes small on mobile devices, AMR sacrifices audio quality through aggressive compression. If you need to edit, archive, or use these recordings professionally, converting to AIFF format gives you uncompressed audio that preserves every detail.

AIFF (Audio Interchange File Format) is Apple's standard for high-quality uncompressed audio. It's widely used in professional audio production, music editing, and archival storage where quality matters more than file size.

How to Convert AMR to AIFF

  1. Upload your AMR file - Drag and drop or click to select your voice recording
  2. Select AIFF as output - Choose AIFF for uncompressed, high-quality audio
  3. Download your AIFF file - Get your converted audio ready for editing

The entire process happens in your browser. No software installation required, and your files remain private.

AMR vs AIFF: Key Differences

Understanding what you gain by converting:

  • Compression - AMR uses lossy compression (4.75-12.2 kbps); AIFF is uncompressed (1411 kbps for CD quality)
  • Quality - AMR is optimized for voice clarity at tiny sizes; AIFF preserves full audio fidelity
  • Editing - AIFF handles multiple edits without quality degradation; AMR degrades with each re-encoding
  • Compatibility - AMR works mainly on mobile; AIFF is standard in Mac/iOS audio applications

In our testing, converting AMR voice memos to AIFF before editing in GarageBand or Logic Pro resulted in noticeably cleaner results when applying effects or noise reduction.

Common Use Cases

Voice Memo Archiving

Phone recordings of interviews, meetings, or personal notes often end up as AMR files. Converting to AIFF creates a future-proof archive format that won't degrade and plays on any Mac or iOS device.

Podcast and Audio Production

If you've recorded phone interviews or voice notes on a mobile device, converting to AIFF before importing into your DAW gives you a cleaner starting point for editing and mixing.

Legal and Medical Transcription

For transcription work where audio clarity matters, converting AMR recordings to AIFF can make speech easier to understand and transcribe accurately.

Quality Considerations

Converting from AMR to AIFF won't magically add quality that wasn't in the original recording. AMR's compression already discards audio information. What AIFF does is prevent any further quality loss during editing and ensure maximum compatibility with professional audio software.

For the best results with voice recordings, consider AMR to WAV as an alternative - WAV offers the same uncompressed quality as AIFF with broader cross-platform support.

Works on Any Device

Convert AMR to AIFF directly in your browser:

  • Mac, Windows, Linux, Chromebook
  • Chrome, Safari, Firefox, Edge
  • iPhone, iPad, Android

No downloads or plugins needed. Your audio files are processed locally and never uploaded to external servers.

Pro Tip

When converting voice memos for podcast use, convert to AIFF first, then apply noise reduction in your DAW. Working with uncompressed audio gives noise reduction algorithms more data to work with, producing cleaner results.

Common Mistake

Expecting dramatic quality improvements after conversion. AMR's compression permanently removes audio data. Converting to AIFF locks in current quality but can't recover what was already lost.

Best For

Mac users who need to edit mobile voice recordings in GarageBand, Logic Pro, or Final Cut Pro. AIFF integrates natively with Apple's professional audio and video software.

Not Recommended

If you just need to play AMR files or share them casually. Converting to AIFF creates much larger files. For simple playback, use a media player that supports AMR or convert to MP3 for smaller size.

Frequently Asked Questions

AMR (Adaptive Multi-Rate) is a compressed audio format primarily used for voice recordings on mobile phones. It's designed to keep voice recordings small while maintaining speech clarity, commonly used for phone call recordings and voice memos.

AIFF (Audio Interchange File Format) is Apple's uncompressed audio format, similar to WAV. It's used in professional audio production, music editing, and archival storage where preserving full audio quality is important.

Converting to AIFF won't restore quality lost during AMR compression, but it prevents further quality degradation during editing. AIFF is lossless, so subsequent edits and exports won't introduce additional compression artifacts.

AMR uses aggressive compression (4.75-12.2 kbps) to minimize file size, while AIFF stores uncompressed audio (typically 1411 kbps for stereo). A 1-minute AMR file might be 100KB, while the same audio in AIFF could be 10MB or more.

Yes. Our converter supports batch processing. Upload multiple AMR files and convert them all to AIFF in a single session without processing each file individually.

Yes. While AIFF is Apple's format, Windows media players and most audio editing software (Audacity, Adobe Audition, FL Studio) can open and edit AIFF files without issues.

Both are uncompressed and equivalent in quality. AIFF is more common on Mac/iOS, while WAV has broader cross-platform support. For Mac-based workflows, AIFF integrates seamlessly with Apple software.

Yes. Conversion happens entirely in your browser using local processing. Your voice recordings are never uploaded to any server, ensuring complete privacy for sensitive audio content.

The converter preserves the original sample rate from your AMR file, typically 8kHz or 16kHz for voice recordings. This maintains the original audio characteristics while providing an uncompressed container.

Yes. AMR files from any source - phone backups, voice recorder apps, or transferred recordings - can be converted to AIFF. The format has remained consistent since its introduction.
