Audio I/O and Waveform Generation
从设备录制和播放音频,读写音频文件,生成波形
Audio Toolbox™ enables real-time audio input and output. Using the enhanced functionality of Audio Toolbox audio I/O, you can interact with the low-latency ASIO™ driver on Windows®, selectively map to and from device channels, and control your device bit depth. To manage a database of audio files, useaudioDatastore
.
You can also generate tunable periodic waveforms to create test signals, control signals, and your own unique sounds.
