pipeline_wav_sdcard录音 #48

Closed DanielLiMing closed 6 years ago

最近在lyrat_v4.2上测试录音,发现编译这个例程运行的时候录音只有10秒(理论上应该是20秒的),而且通过其他播放器播放的时候播放速度比录的声音要快,这是什么原因啊?

Hi @DanielLiMing
I have not reproduced this on the latest adf, can you show more detail, like rec.wav mediainfo ?

播放语速明显比正常语速要快,而且音质也不是很好!日志没有什么异常信息,我记得之前的是能正常播放的!(原音乐名称:白羊)

Hi @DanielLiMing 你的意思是你录音的时候在播放一个歌曲,然后录下来之后和原来的音频对比语速快,音质不好,是吗? 我也做了同样尝试,没有发现你说的问题,能否帮忙将录音文件传上来看下。

rec.zip 我又在新的环境中重新配置ADF发现结果还是有点快,录下来的文件只有10s,
