"This module provides support for reading and writing AIFF and AIFF-C files. "

"AIFF is Audio Interchange File Format, a format for storing digital audio "

"samples in a file. AIFF-C is a newer version of the format that includes "

"the ability to compress the audio data."

msgstr ""

#: ../../library/aifc.rst:21

msgid ""

"Audio files have a number of parameters that describe the audio data. The "

"sampling rate or frame rate is the number of times per second the sound is "

"sampled. The number of channels indicate if the audio is mono, stereo, or "

"quadro. Each frame consists of one sample per channel. The sample size is "

"the size in bytes of each sample. Thus a frame consists of ``nchannels * "

"samplesize`` bytes, and a second's worth of audio consists of ``nchannels * "

"samplesize * framerate`` bytes."

msgstr ""

#: ../../library/aifc.rst:29

msgid ""

"For example, CD quality audio has a sample size of two bytes (16 bits), uses "

"two channels (stereo) and has a frame rate of 44,100 frames/second. This "

"gives a frame size of 4 bytes (2\\*2), and a second's worth occupies "

"must be opened for reading, or ``'w'`` or ``'wb'`` when the file must be "

"opened for writing. If omitted, ``file.mode`` is used if it exists, "

"otherwise ``'rb'`` is used. When used for writing, the file object should "
