Audio Transcription

Overview

Relay.app leverages OpenAI Whisper to provide a simple interface for transcribing audio files into text. Users can upload audio files, and the system processes them using Whisper's state-of-the-art transcription technology, delivering accurate text results.

Supported File Types

Our transcription steps support the following file types, based on what OpenAI Whisper supports: MP3, WAV, M4A, OGG, MPEG, MP4, MPGA

Note: Whisper's transcription quality may vary based on the clarity and quality of the input audio.

File Size and Duration Guidelines

File Size Limit

  • Maximum size: 25MB per audio file.

Approximate Audio Length

The duration of audio that can be processed depends on the format and compression quality:

  • High-compression formats (e.g., MP3, OGG): Up to 30 minutes of audio.

  • Low-compression formats (e.g., WAV): Shorter durations, typically 10–20 minutes, due to larger file sizes.

Best Practices

  • Ensure the audio is clear and free from excessive background noise for optimal transcription quality.

  • Use shorter clips for faster processing.

  • Prefer MP3 or M4A formats for longer durations within the file size limit.

Troubleshooting

Common Issues:

  • File exceeds 25MB: Compress or trim the audio file using an audio editing tool before uploading.

  • Unsupported format: Convert the file to one of the supported formats using free tools like Audacity or online converters.
