Convert gsm to txw

What is the difference between .gsm and .txw?

Description: A lossy file format used to compress speech in Global Standard for Mobile (GSM) telecommunications. It is very effective for reducing audio file size. However, encoding and decoding audio signals severally is discouraged as the final product will have a lot of noise. Popular with some voice mail software but it is CPU intensive.; The TXW file format is associated with the Yamaha TX16W, a digital sampling keyboard produced in the late 1980s. These TXW files contain audio data that is specifically formatted for use with the TX16W sampler. Essentially, a TXW file stores a sample or a collection of samples, including their associated parameters such as loop points, velocity layers, and other settings that are necessary for the sampler to correctly playback the sounds. The format is proprietary to Yamaha.
