Sound files have built-in descriptors known as headers. The following functions return the information in the header. In each case the argument to the function is the full file name of the sound file.

mus_sound_samples(file)#: samples of sound according to header

mus_sound_framples(file)#: samples per channel

mus_sound_datum_size(file)#: bytes per sample

mus_sound_data_location(file)#: location of first sample (bytes)

mus_sound_chans(file)#: number of channels (samples are interleaved)

mus_sound_srate(file)#: sampling rate

mus_sound_header_type(file)#: header type (aiff etc)

mus_sound_sample_type(file)#: sample type (alaw etc)

mus_sound_original_sample_type(file)#

mus_sound_comment_start(file)#: comment start (bytes) if any

mus_sound_comment_end(file)#: comment end (bytes)

mus_sound_length(file)#: true file length in bytes

mus_sound_fact_samples(file)#

mus_sound_type_specifier(file)#: original header type identifier

mus_sound_block_align(file)#

mus_sound_bits_per_sample(file)#: bits per sample

mus_sound_set_chans(file, val)#: set number of channels for file

mus_sound_set_srate(file, val)#: set the sample rate of the file

mus_sound_set_header_type(file, mus_header)#: set header type of file

mus_sound_set_sample_type(file, mus_sample)#: set sample type of file

mus_sound_set_data_location(file, val)#: set the data location of the file

mus_sound_set_samples(file, val)#: set number of samples in the file

mus_header_type_name(header_type)#: get file header type as a string

mus_header_type_to_string(header_type)#: convert a header enum to a string

mus_sample_type_name(samp_type)#: get file sample type as a string

mus_sample_type_to_string(samp_type)#: convert a sample enum to a string

mus_sample_type_short_name(samp_type)#: convert a sample enum to a short name string

mus_sound_comment(file)#: retrieve file comment if one exists

mus_bytes_per_sample(samp_type)#: bytes per sample

mus_sound_duration(file)#: sound duration in seconds

mus_sound_override_header(file, srate, chans, sample_type, header_type, location, size)#: override the header information

mus_sound_loop_info(filename)#: 8 loop vals (mode,start,end) then base-detune and base-note (empty list if no loop info found)

mus_sound_set_loop_info(filename, info)#: set file loop information

mus_sound_open_input(filename)#: open file to read as input

mus_sound_open_output(file, srate, chans, sample_type, header_type, comments)#: open file for output

mus_sound_reopen_output(file, srate, chans, sample_type, header_type, location)#: reopen a file for further input

mus_sound_close_input(fd)#: close file for input

mus_sound_close_output(fd, bytes_of_data)#: close file for output

mus_set_clipping(new_value)#
