Depending on your telephone system, you need to use "tones2alaw" or "tones2ulaw". +There are two frequencies to specify "frq1" and "frq2". If only one frequency should be +used, enter 0 for "frq2". The "length" specifies the total length of the tone in samples. 8000 +samples are one second. 2000 samples are 1/4 of a second. "fade in" and "fade out" is used to +make the start and stop of the tone soft. If "fade in" is 800, the sound will fade in +within 1/10 of a second. +This makes tones very smooth and avoids the ‘click’ sound at the beginning. +"fade out" respectively. Whatever specified for "fade in" and "fade out", the tone will +be as long as given at "length". If you don’t want to use fades, set "frq1" and "frq2" to +"0". I suggest at least 50 sample for fade to silence. +.br +The given file will be appended to "alaw file" or "ulaw file". If you like +to create a new one, but the name still exist, delete the file and then start creating it. This +is useful to create a sample with more than one tone. Example: A busy tone normally is made out of +1/2 second of a tone, and one 1/2 second of silence. To add silence, just enter 0 for "frq1" +and "frq2". +.br +It is also possible to convert a wave file to a-law or mu-law. The wave file +must have a sampling rate of 8000. It doesn’t matte what bit-resolution or how many +channels it has (stereo or mono). The sampling rate will not be converted, so it must be +8000 samples/second. The resolution should be 16 bits for best quality. a-law and +mu-law have better resolution than 8 bits. The data of a-law and mu-law is 8 bits +sample, but since it is quantised, the quality will be 12 bits. 12 bits sounds almost as good as 16 +bits. Wave files are only available with 8 or 16 bits resolution. +.br +The use of a-law or mu-law files, result in a faster processing, since the +samples must not be converted into a-law or mu-law for ISDN use. ISDN uses only a-law or mu-law +samples. +.SH SEE ALSO +http://www.linux-call-router.de/doc.html +.SH AUTHOR +This minimal man page was written by Victor Seva + +.br +from documentation created by Andreas Eversberg -- cgit v1.2.3-55-g7522
