The 8-bit uLaw to 16-bit PCM and the 13-bit-PCM to 8-bit uLaw
|
||
|
|
tables were lifted from the rsynth-2.0 sources. The README says:
|
||
|
|
|
||
|
|
This is a text to speech system produced by integrating various pieces
|
||
|
|
of code and tables of data, which are all (I believe) in the public domain.
|
||
|
|
|
||
|
|
The bulk of the intergration was done by myself, that is Nick Ing-Simmons.
|
||
