Signal Processing

Signal Processing

Signal processing consists of the modification, recording, analysis and synthesis of audio signals using waveform, spectrum or time-frequency representation.

This section contains the following topics:

File/Signal Management
File or signal management allows you to load and prepare the sound files to be processed in the software.
Signal Playback
Sound: Analysis and Specification allows you to listen to any signal with temporal information whatever its physical unit. The Playback controls and the Playlist help you to listen to signals.
Sound Recording
This section provides you with information on recording sound using an acquisition device.
Sound Generation
Sound: Analysis and Specification allows you to generate audio signals in the WAV format from various processing: mixing, adding signals in channels, extracting signal from channel.
Signal Modification
Sound: Analysis and Specification allows you to modify temporal and spectral signals and time frequency representations. When modifying a signal or a representation, you can correct or delete undesired components. You can also add effects or change signal representations.
Signal Conversion
Sound: Analysis and Specification allows you to convert temporal signals by using a set of predefined conversion processes.
Signal Profiles
In SAS, you can associate so-called profiles with any signal. A profile is a signal that has a relationship with, and has the same duration as the signal with which you want to associate it.
