SoundDeviceSamplesGenerator
¶ Bases:
acoular.tprocess.SamplesGenerator
Controller for sound card hardware using sounddevice library
Uses the device with index
device
to read samples from input stream, generates output stream via the generatorresult()
.-
device
= Int(0, desc="input device index")¶ input device index, refers to sounddevice list
-
numchannels
= Long(1, …¶ Number of input channels, maximum depends on device
-
collectsamples
= Bool(True, …¶ Indicates if samples are collected, helper trait to break result loop
-
sample_freq
= Property( …¶ Sampling frequency of the signal, changes with sinusdevices
-
overflow
= Bool(False, …¶ Indicates that the sounddevice buffer has overflown
-
running
= Bool(False, …¶ Indicates that the stream is collecting samples
-
stream
= Any¶ The sounddevice InputStream object for inspection
-
device_properties
()¶ - Returns
- Dictionary of device properties according to sounddevice
-
result
(num)¶ Python generator that yields the output block-wise. Use at least a block-size of one ring cache block.
- Parameters
- numinteger
This parameter defines the size of the blocks to be yielded (i.e. the number of samples per block).
- Returns
- Samples in blocks of shape (num,
numchannels
). The last block may be shorter than num.
- Samples in blocks of shape (num,
