将音频和机器人转换成 mp3 或 AAC
原标题:Converting audio on android to mp3 or AAC

I am recording audio from mic and save it to .mp4 - it is AMR format. How to convert this audio to mp3 or AAC? I saw this post and I did not understand it - I am new in android.

我一整天都在谷歌,却一无所获。 也许某个好人可以解释, 并以此为例, 数以百计的人会感激不尽!

谢谢

您能否避免记录到 AMR ( 丢失格式), 并记录原PCM 样本? 然后直接将这些PCM 样本送入 AAC 或 MP3 编码器, 会提高您的质量。 第一次进行 AMR, 然后AAC 两次发布信息 。
