Test Your Knowledge in Computers #268
Difficulty: Easy
In 1936, Turing published his paper 'On Computable Numbers, with an Application to the Entscheidungsproblem'. In this paper, Turing reformulated Kurt Godel's 1931 results on the limits of proof and computation, replacing Godel's universal arithmetic-based formal language with the formal and simple hypothetical devices that became known as Turing machines.

NAME
pvf tools - utilities to convert various sound formats DESCRIPTION
The pvf tools are a collection of tools to convert vgetty modem data to and from the 'raw modem data' format, and from that to and from various audio file formats (like .au or .wav). In addition, there are some tools to manipulate pvf files, like speed up files or cut off trailing noise. A list of commands is below in the "see also" section. You can run those commands with the -h switch for available options. Please also look at the individual contributed man pages. SEE ALSO

auconvert [-file <format>] [-data <format>] [-rate <sample rate>] [-comment <comment>] [-raw <data format> <num tracks>] [-volume <per- cent>|`max'] [-?] [<input file>] [<output file>] DESCRIPTION
The auconvert program can be used to convert from one sound file format, and/or data format to another. It can also change the comment, sampling rate, and volume of a sound file. Finally, auconvert can be used to convert raw audio data into a sound file. If no input file name is given, standard input will be used. If no output file name is given, the original file will be replaced by the converted file or standard out will be used if the input is coming from standard input. OPTIONS
The following options may be used with auconvert: -file format The output file format. The -? option will display a list of valid file formats. -data format The output data format. The -? option will display a list of valid data formats. Note that each file format may only support selected data formats. -rate sample rate The output sampling rate (in hertz). -comment comment The comment to be stored in the output file. -volume <percent>|`max' The volume option can be used in two ways. If the argument is a percentage, the output file volume will be converted to the speci- fied percentage of the input volume. If the argument is the string `max', the output file volume will be converted to its maximum level. -raw <data format> <num tracks> This option is used to convert raw audio data into a sound file. <data format> is the data format of the raw data. <num tracks> specifies the number of tracks in the raw data.
