This DataPlugin supports reading / importing and writing / exporting of audio WAVE files.
This DataPlugin can read and write Audio WAVE files with 1, 2 or more channels. Audio WAVE files play recorded sound in Windows Media Player and similar applications. It also supports Float_IEEE format sound files.
Writing audio files:
- The Audio DataPlugin will write all channels of the first group to the wav file.
- The sampling rate can be controlled by adding the property "Sampling_Rate" to the group and apply the desired sampling rate. The default is 44100.
- Also the bit resolution can be adapted by assigning 8, 16, 24 or 32 to the group property "Bits_Per_Sample". The default is 32.
Note:
- The Audio DataPlugin uses the Microsoft DirectShow API. Different machines can have different versions of DirectShow filters, which can introduce slightly different decoded values (DirectShow filters can be updated along with applications such as Microsoft Windows Media Player, Microsoft DirectX, etc.).
