问题 Can we use mp3 files for the voice recognition process without using wav files? or can we generate a wav file from a mp3 and then do the voice recognition without a serious impact on the accuracy? The problem is I need to minimize the load transferred through the network in my application. Will the information which is lost in the conversion be a huge factor for accuracy? 回答1: Can we use mp3 files for the voice recognition process without using wav files? Not directly.

How to record audio in format of mp3/m4a JavaScript- recorder.js

由 可紊 提交于 2019-12-08 10:03:29
In recorderjs rec.exportWAV([callback][, type]) is used to generate a Blob object containing the recorded audio in WAV format. But the WAV file is taking large space, for 30sec it is approximately 1mb. So I want to record the audio in format of mp3/m4a which takes less space. Is there any way to record audio in format of mp3/m4a. rampravesh i think you should check this link : HTML5 record audio to file here u can change the audio type like this : type = type || config.type || 'audio/wav'; Recorder.js does NOT support encoding captured audio as mp3. It can only record 16 bit mono or stereo
