In the previous chapter, the focus was on learning fundamentals of audio processing. It introduced us to the GStreamer multimedia framework. We applied this knowledge to develop some frequently needed audio processing tools. In this chapter, we will go one step further by developing tools for adding audio effects, mixing audio tracks, creating custom music tracks, and so on.
In this chapter, we shall:
Learn how to control a streaming audio.
Spice up the audio by adding effects such as fading, echo, and panorama.
Work on a project where a custom music track will be created by combining different audio clips.
Add visualization effect to a streaming audio.
Mix two audio streams into a single track. For example, mix an audio containing only a vocal track with an audio containing only background music track.
So let's get on with it.
