Audio Compressor

About Audio Compressor

A single WAV podcast episode can be 500 MB or more. Converting to MP3 helps, but you may still want further optimization. Davirix Audio Compressor lets you fine-tune bitrate (from 320 kbps studio quality down to 64 kbps for voice-only content) and sample rate to hit your target file size. The tool shows a before/after comparison so you can judge whether the compressed version sounds acceptable. For voice content (podcasts, meetings), 96 kbps in mono sounds surprisingly clean and produces tiny files.

Key Features

• Adjustable bitrate from 32 to 320 kbps
• Sample rate options: 22.05, 44.1, 48 kHz

Frequently Asked Questions

What bitrate should I use?

For music: 192-256 kbps. For podcasts/voice: 96-128 kbps. For phone-quality voice: 64 kbps. Higher is always better quality but larger files.

Does compression damage the audio?

Lossy compression removes inaudible frequencies. At 192+ kbps, most people can't tell the difference from the original.

Can I compress WAV to WAV?

WAV is uncompressed by definition. To reduce a WAV file, convert it to MP3, AAC, or OGG at your target bitrate.
