audiofinder not able to read some aiff files

Returns a namedtuple() (nchannels, sampwidth, framerate, nframes, comptype, compname Return a bytes array of length 4 describing the type of compression used in the audio file.

Return the number of audio frames in the file. Return the sampling rate (number of audio frames per second). Return the size in bytes of individual samples. Return the number of audio channels (1 for mono, 2 for stereo). The aiff or aiff-c read object uses following functions getnchannels() Like writeframes(), except that the header of the audio file is not updated.įollowing program creates an AIFF file import aifc, struct The argument is a tuple consisting of the various parameters. compression types supported - b'NONE', b'ULAW', b'ALAW', b'G722'. compression is not possible for AIFF file.

Specify the number of frames that are to be written to the audio file. Specify the sampling frequency in frames per second. Specify the size in bytes of audio samples. Specify the number of channels in the audio file. The object with write mode uses following functions aiff() It should be 'w' or 'wb' when the file must be opened for writing. This function opens an AIFF or AIFF-C file and return an object instance for reading/writing audio data depending on mode.It must be 'r' or 'rb' if the file must be opened for reading. Audio data of 1 sec is channels * samplesize * framerate bytes.įollowing functions are defined in aifc module: aifc.open() Thus a frame consists of channels * samplesize bytes. The sample size: size in bytes of each sample. The number of channels: indicate if the audio is mono, stereo, or quadro.įrame : consists of one sample per channel. The sampling rate or frame rate: number of times per second the sound is sampled. Its newer version AIFF-C has the ability to compress the audio dataĪudio file has number of parameters describing the audio data. AIFF format is for storing digital audio samples in a file. Various functions in aifc module provide support for reading and writing AIFF (Audio Interchange File Format) and AIFF-C files.
