Tip: When using EQ, it’s essential to listen to the audio carefully to avoid over-boosting or under-boosting specific frequencies.
Using Compression to Even Out Audio Levels
Compression is a process of reducing the dynamic range of an audio signal to even out the levels. By compressing the audio, you can bring up the overall level and reduce the risk of distortion.
- Threshold: Set the threshold to determine the level above which the compressor starts to reduce the signal.
- Ratio: Set the ratio to determine the amount of compression applied to the signal.
- Attack and Release: Adjust the attack and release times to control how quickly the compressor responds to the signal.
Tip: When using compression, it’s essential to adjust the settings carefully to avoid over-compressing the audio.
Conclusion
