Convert sound file into wav with specific bitrate and cut specific part of the file

由 删除回忆录丶 提交于 2020-01-14 05:37:06
问题 I have some sound file(basically mp3 but it can be of any bitrate). I need to method to extract specified part of input file(not more than 40 seconds) into 8 bit mono wav output . I would appreciate any help or advice in choosing java library to do that. 回答1: You can use JavaLayer to decode mp3 into wav. Cutting a 40-second clip from a wav shouldn't be a problem. You can find some hints about mixing stereo to mono here: http://www.jsresources.org/examples/SingleChannelStereoConverter.html

问题 I have an mp3 file as byte array. How to turn it back to a sound and play using javascript? Thanks 回答1: As far as I know this is decidedly non trivial. You can turn the array into a data URI, and then play it back normally. You can post it back to a server to do the encoding and play it back normally.
