The following output channel specifications accomplish this mapping. This program allows direct specification of the gains for 12 output channels and 20 input channels. By default, the output file contains a standard audio file information string. This information can be changed with the information string which is specified as one of the command line options. Structured information records should adhere to the above format with a named field terminated by a colon, followed by numeric data or text.
Comments can follow as unstructured information.
If the information string starts with a record delimiter, the header information string is appended to the standard header information. If not, the user supplied header information string appears alone. Copy audio file abc.au to new.au. The number of channels in the output file is the same as the number of channels in the input file. Concatenate audio data.
