Examples

1. Web-Ready Podcast Export

Podcast Producer
Background
A producer has a 70MB WAV file of a recorded interview that needs to be uploaded to a website.
Problem
The file is too large for quick loading and consumes unnecessary bandwidth.
How to Use
Upload the WAV file and select a 128 kbps bitrate for a balance of quality and size.
Example Config
bitrate: 128, sampleRate: 48000, channels: auto, keepMetadata: true
Outcome
A compact Opus file that retains high audio clarity and original metadata, ready for web streaming.

2. Mono Voice-Over Optimization

Content Creator
Background
A creator has a stereo WAV voice-over file that needs to be converted to a smaller format for a mobile app.
Problem
Stereo is unnecessary for a single voice track and doubles the file size.
How to Use
Upload the file, set the channel option to Mono, and choose a 96 kbps bitrate.
Example Config
bitrate: 96, sampleRate: 48000, channels: 1, keepMetadata: false
Outcome
A highly compressed, mono Opus file perfectly optimized for mobile app storage.
