1. Noise reduction - This technique involves removing unwanted background noise from an audio signal. This can be achieved using specialized software that analyzes the sound waves and removes or filters out unwanted noise.
2. Equalization - This technique involves adjusting the frequency response of an audio signal to improve its tonal balance. This can be used to boost or cut certain frequencies and can be particularly useful in removing unwanted rumble or hum.
3. Compression - This technique is used to reduce the dynamic range of an audio signal. This can be useful in reducing the difference between the loudest and quietest sounds in an audio recording and can help to make it sound more consistent.
4. De-essing - This technique is used to reduce or eliminate harsh “s” sounds in a voice recording. This is achieved using specialized software that detects the frequency of the “s” sound and reduces it.
5. Reverb removal - This is a technique used to remove unwanted echoes or reverberations from an audio signal. This can be useful in improving the clarity and definition of an audio recording.
6. Mastering - This technique involves taking a final mix of an audio recording and optimizing it for distribution. This can involve adjusting levels, equalization, compression, and other parameters to ensure that the final product sounds as good as possible across a range of playback systems.
