Audio In channel node
Receives audio input from the analog audio ports or the digital port.
This CHOP receives audio input from the analog audio ports or the digital port. It always outputs time sliced audio data. If you want to record the data, use a Record CHOP.
Note | Receiving audio from an audio CD using a CD-ROM is not supported. Instead, feed the audio through the Audio-in port. |
Parameters
Audio
Audio Source | Selects the audio port to listen to.
| ||||||
Audio Format | Selects mono, stereo, or 4 channel mode. 4 Channel mode is not available on all systems. This parameter also determines how many channels are created (1, 2 or 4). | ||||||
Use Global Sample Rate | If on, audio is sampled at the system input sample rate. Otherwise, the next parameter allows you to change the system input sample rate. Note that this may disrupt other applications using the audio system. This parameter does not set the actual channel sample rate; that is set by the 'Sample Rate' parameter in the Channel tab. These two sample rates can differ; the audio is resampled to the channel sample rate. | ||||||
Input Sample Rate | The sample rate of the audio input system. | ||||||
Record Queue | The number of seconds of audio to buffer at the input. Input audio will be delayed by this amount of time. A large buffer allows for slower cooking; if the buffer is too small, gaps and pops will be heard in the audio. |
Levels
Channel 1-4 | Each channel can be scaled separately by any factor. |
Input Attenuation | This parameter controls the audio system hardware’s input attenuation, which corresponds to the “record level” of a tape recorder. 0 is the lowest recording level, and 1 is the highest recording level. If you notice audio is being clipped at +-1, lower this value. |
Channel
Channel 1-4 Name | The names of the audio channels. |
Sample Rate | The sample rate of the audio channels. This may be different from the audio input’s sample rate; the input audio will be resampled to the CHOP’s sample rate. |
Extend Left, Right | The extend conditions for the audio channels. |
Default Value | The default value for the 'Default Value' extend condition. |
