Generating custom dataset from multiple mp3 files

[dain7672]

Hi, thanks for amazing work.

I am currently working on generating custom dataset by converting multiple mp3 files to MIDI & CPs.
And checked google magenta's onsets and frames you mentioned.
I want to convert about 1K mp3 files into MIDIs at once, but their scripts seems to support only wav format.
It would be better if it supports mp3 format because it is much lighter than wavs.
Also I am not sure whether the scripts work well with 1k files at once.

If it is okay, could you share some tips how you transcribed multiple files?
Thanks.

嗨，感谢您的出色工作。

我目前正在通过将多个 mp3 文件转换为 MIDI 和 CP 来生成自定义数据集。并检查了你提到 的谷歌洋红色的起始点和框架。 我想一次将大约 1K 的 mp3 文件转换为 MIDI，但他们的脚本似乎只支持 wav 格式。 如果它支持mp3格式会更好，因为它比wavs要轻得多。 另外我不确定这些脚本是否可以同时处理 1k 个文件。

如果可以，您能否分享一些如何转录多个文件的技巧？ 谢谢。

Maybe you can try ffmpeg
