        FixedSizeInputAdapter

Utility to make it easier to write processors which require fixed-sized input buffers.

Instance Methods

[hide private]

__init__(self, buffer_size, channels, pad=False)
Construct a new adapter: buffer_size is the desired buffer size in frames, channels the number of channels, and pad indicates whether the last block should be padded with zeros.

source code

blocksize(self, input_totalframes)
Return the total number of frames that this adapter will output according to the input_totalframes argument

source code

process(self, frames, eod)
Returns an iterator over tuples of the form (buffer, eod) where buffer is a fixed-sized block of data, and eod indicates whether this is the last block.

init(self, buffer_size, channels, pad=False)
(Constructor)

source code

Construct a new adapter: buffer_size is the desired buffer size in frames, channels the number of channels, and pad indicates whether the last block should be padded with zeros.

Overrides: object.__init__

process(self, frames, eod)

source code

Returns an iterator over tuples of the form (buffer, eod) where buffer is a fixed-sized block of data, and eod indicates whether this is the last block. In case padding is deactivated the last block may be smaller than the buffer size.
