📁 Supported Audio Formats

🔄

Automatic Format Conversion

New! Transcriptr now automatically converts unsupported formats (M4A, AAC, MP4, WMA, etc.) to MP3 before transcription. No manual conversion needed!

✅ Directly Supported (Fast Processing)

  • MP3 - Most common audio format
  • WAV - Waveform Audio File
  • FLAC - Free Lossless Audio Codec
  • OGG - Open-source audio format

🔄 Auto-Converted (Slightly Longer Processing)

  • M4A - MPEG-4 Audio (iPhone recordings)
  • AAC - Advanced Audio Coding
  • MP4 - MPEG-4 with audio track
  • WMA - Windows Media Audio
  • AIFF - Audio Interchange File Format
  • CAF - Core Audio Format (macOS)

💡 Tip: Directly supported formats (MP3, WAV, FLAC, OGG) process immediately, while other formats are automatically converted first.

⏱️ Processing Time: Auto-converted files take 30-60 seconds longer due to the conversion step, but the process is fully automated.

🔄 Audio Conversion Process

When you upload unsupported formats like M4A or AAC, here's what happens automatically:

1

Format Detection

System automatically detects if conversion is needed

2

Secure Upload

3

4

🔧 Troubleshooting

Upload Issues

• Most audio formats are now supported (MP3, WAV, FLAC, OGG, M4A, AAC, etc.)

• If your format isn't supported, try converting to MP3 or WAV first

• Check that the file size doesn't exceed the upload limit

• Try refreshing the page if uploads are failing

• Verify your internet connection is stable

Transcription Failures

• Check your internet connection and try again

• Ensure the audio quality is clear and audible

• Try reducing the batch size in advanced options

• For persistent issues, use the feedback form to report bugs

Browser Compatibility

• Use modern browsers: Chrome, Firefox, Safari, or Edge

• Enable JavaScript for full functionality

• Clear browser cache if experiencing issues

• Disable ad blockers if uploads are blocked

Performance Tips

• Shorter audio files (under 1 hour) process faster

• Use lower batch sizes for large files to avoid memory issues

• Close other browser tabs to free up resources

• Consider splitting very long recordings into segments
