Change Audio Volume
This lesson is part of Web Developer Tools · All levels
Summary
Change audio volume to increase or decrease the level of loudness. Changes are usually measured in decibels (dB); positive values magnify the volume, negative values reduce it. If the volume is raised too high, the peak of the wave can be cut off so that the sound breaks. For a balanced result, use normalization or compression rather than over-increasing gains.
Key points
- Gain measured in dB: +6 dB approximately double the amplitude
- Negative values lower the volume without changing the duration
- The volume is too high causing clipping and distortion
- Normalisation adjusted peak levels to be consistent
- Always listen to the results with headphones before publishing.
