When developing a call center, you need to play the voice. You need to convert the wav format of your recorded voice to the gsm format. asterisk also supports the wav format, however, it is unclear why the wav file cannot be played if it is larger, so it is only converted to the gsm format.Command: sox 00.wav-r 8000-c 1 00.gsm resample-qlThe following is an article source found on the Internet.Sox is the most famous Open Source audio file format conve

is no fixed bit rate, and the compression software determines the bit rate based on the audio data during compression. This is an algorithm developed by Xing. They use high bitrate encoding for the complex part of a song and low bitrate encoding for the simple part. Although the idea is good, it is a pity that the Xing encoder's VBR algorithm is very poor, and the sound quality is far from that of CBR. For

Video and audio processing has always been an important application of computers in multimedia. Traditionally, it is the world of Unix workstations. BecauseLinuxIs a variant of a Unix operating system. To some extent, it is inherently applicable to the graphic market. At present, most of the market has been divided by Linux workstations. Linux has become a substitute for Unix systems on personal computers and can be used to replace expensive systems.

sound quality of a digital audio depends on the sample rate recorded or stored. Most of us are familiar with the MP3 digital audio format. The higher the bit rate or sample rate, the better the sound quality. However, a higher bit rate also means that the file is larger.The techniques described in this article relate to the layering of digital audio files that c

In game development, I learned from materials and books that two formats of playing audio can be used in our game development: MediaPlayer and SoundPool! PS: Of course, there is another JetPlayer, but the format of the file to be played is quite troublesome, so I will not explain it here. If you are interested, you can study it on your own; Run: MediaPlayer and: SoundPool class! What are their advantages and disadvantages? Or, which one is better
