Detailed Description
Internal version of the BelaContext struct which does not have const elements, so it can be modified by the code. When it's passed to the user code, it is typecast to the standard BelaContext.
Important: make sure this retains the same structure as BelaContext!
Member Data Documentation
| float* InternalBelaContext::audioIn |
Buffer holding audio input samples.
This buffer may be in either interleaved or non-interleaved format, depending on the contents of the BelaInitSettings structure. Note: this element is available in render() only.
| float* InternalBelaContext::audioOut |
Buffer holding audio output samples.
This buffer may be in either interleaved or non-interleaved format, depending on the contents of the BelaInitSettings structure. Note: this element is available in render() only.
| float* InternalBelaContext::analogIn |
Buffer holding analog input samples.
This buffer may be in either interleaved or non-interleaved format, depending on the contents of the BelaInitSettings structure. Note: this element is available in render() only.
| float* InternalBelaContext::analogOut |
Buffer holding analog output samples.
This buffer may be in either interleaved or non-interleaved format, depending on the contents of the BelaInitSettings structure. Note: this element is available in render() only.
| uint32_t* InternalBelaContext::digital |
Buffer holding digital input/output samples.
Note: this element is available in render() only.
| uint32_t InternalBelaContext::analogFrames |
Number of analog frames per period.
This will be 0 if analog I/O is disabled.
| uint32_t InternalBelaContext::analogInChannels |
Number of input analog channels.
This will be 0 if analog I/O is disabled.
| uint32_t InternalBelaContext::analogOutChannels |
Number of output analog channels.
This will be 0 if analog I/O is disabled.
| float InternalBelaContext::analogSampleRate |
Analog sample rate in Hz.
The analog sample rate depends on the number of analog channels used. If 8 channels are used, the sample rate is 22050. If 4 channels are used, the sample rate is 44100. If 2 channels are used, the sample rate is 88200. If analog I/O is disabled, the sample rate is 0.
| uint32_t InternalBelaContext::digitalChannels |
Number of digital channels.
Currently this will always be 16, unless digital I/O is disabled, in which case it will be 0.
| uint64_t InternalBelaContext::audioFramesElapsed |
Number of elapsed audio frames since the start of rendering.
This holds the total number of audio frames as of the beginning of the current period. To find the current number of analog or digital frames elapsed, multiply by the ratio of the sample rates (e.g. half the number of analog frames will have elapsed if the analog sample rate is 22050).
| uint32_t InternalBelaContext::flags |
Other audio/sensor settings.
Binary combination of flags including:
BELA_FLAG_INTERLEAVED: indicates the audio and analog buffers are interleaved
BELA_FLAG_ANALOG_OUTPUTS_PERSIST: indicates that writes to the analog outputs will persist for future frames. If not set, writes affect one frame only.
