Large audio files can exceed email attachment limits (typically 20-25MB). Here's how to compress audio files without sacrificing too much quality — no software needed.
Audio File Size Quick Guide
- → WAV (uncompressed): ~10MB per minute
- → MP3 at 320kbps: ~2.4MB per minute
- → MP3 at 128kbps: ~0.9MB per minute
- → MP3 at 64kbps: ~0.5MB per minute (voice quality)
How to Compress Audio Online
- 1. Open FileCurve Audio Compressor
- 2. Upload your audio file (WAV, FLAC, MP3, AAC)
- 3. Choose bitrate: 128kbps for music, 64kbps for voice/podcasts
- 4. Click Compress and download the smaller MP3
Bitrate Guide
- 320kbps: CD quality, barely distinguishable from lossless. Large files.
- 192kbps: High quality, suitable for music sharing. Good size/quality ratio.
- 128kbps: Standard MP3 quality. Fine for most listening. Recommended for email.
- 64kbps: Voice/podcast quality. Noticeably compressed but acceptable for speech.
Alternative: Trim the Audio First
If you only need to send a specific section of the audio, use the Trim Audio tool to cut it. A shorter clip = smaller file regardless of compression.
