Fix distorted or quiet SHOUTcast audio
Improve audio clarity and avoid clipping when streaming music or vocals.
Reviewed · Follow the instructions supplied with your own rental.
Before you start
Use a familiar loud passage and your normal speaking or singing volume. Have headphones and a separate listener ready, and check the input, mixer and encoder as separate stages.
Steps
- Play a loud section of your music and speak into the microphone at your usual performance volume.
- Check the microphone or audio interface first, then the mixer, then the broadcaster. Reduce gain wherever a clipping indicator appears; leave room for louder peaks.
- If the stream is too quiet, check for muted channels, low source levels, or a mixer crossfader favouring the wrong input. Raise levels gradually while watching the meters.
- In BUTT, use Mixer to balance the input devices. The main Gain slider also affects Master Gain; adding excessive gain can increase noise.
- Use headphones to compare music and voice, then ask a listener to check the actual stream. Your headphone volume alone does not show the broadcast level.
- If the problem remains, send TJ Lusch your software name, audio-device details, and a screenshot of the levels in a private Second Life message.
Check it worked
A listener hears clear music and speech without clipping, excessive noise or one source overwhelming the other. Your headphone volume is not the transmitted level.
If it does not work
- Clipping indicator: reduce gain at that stage.
- Quiet signal: look for mute controls, low source gain and crossfader position before boosting everything.
- Voice is delayed or repeated: inspect the monitoring and routing path.
- Distorted source: changing stream bitrate will not repair it.
Notes and references
Good to know: Changing the stream bitrate will not fix a distorted audio source. Correct the source or mixer levels before adjusting the encoder.
