What Is an Audio Compressor?

An audio compressor reduces the file size of music, voice recordings and other audio so they upload faster, use less storage and are easier to share. By lowering the bitrate or re-encoding to a more efficient format, you can shrink an MP3, WAV or OGG file significantly while keeping it sounding clear.

EazyStudio's audio compressor processes everything in your browser, so your recordings are never uploaded to a server. It is perfect for podcasters, musicians and anyone who needs to email or post audio within size limits.

Frequently Asked Questions

Some quality reduction is unavoidable when you lower the bitrate, but at moderate settings the difference is hard to hear. Choose a higher bitrate to preserve quality or a lower one for the smallest file.
The tool works with common formats including MP3, WAV and OGG.
No. Compression runs locally in your browser, so your audio never leaves your device.
It depends on the original format and the bitrate you choose. Converting a large WAV file to a compressed MP3, for example, can reduce size by 80% or more.
Because processing happens in your browser, very large files use more memory. Most typical recordings compress without any issue.
