Recently made a voice changer of the project, which involves a lot of audio-related knowledge, afraid of a long time to remember, write down the memo.1. Encoding of The VoiceVoice recording when to choose an encoding format, because the mobile side of the reason, this encoding format needs to meet the compression ratio, sound quality is better (at least can be heard after the voice), but also the difficulty of coding small.We chose several formats earlier: A

The project needs to use the Baidu voice interface in the web to achieve speech recognition, the use of such a technical solution, but the implementation encountered a lot of problems, found that most of the online articles are only in detail the official example samples provided, the actual development did not provide any valuable advice, and recorder.js is not directly suitable for the voice interface of Baidu AI, so this article will be developed in the details of the record with this, welcom
