日本と海外をつなぐクラウドソーシング

If you can use a software that can change the speed of MP3 files, this is a very simple task.

I have a lot of audio files(Japanese. about 200 files it contains 10 seconds file and 20 minutes file). It is a CD15 sheets minute in total.

Please convert all audio files to 2x / 4x / 6x / 8x one by one. (So you will make about 800 files. ) You should do pitch correction.
Reward is 3000 yen.

If you apply, please create a 4x and 8x sample file(sample is English).
I will determine the hires considering　the sound quality, pitch,the clarity.
I will send you the files by dropbox or google drive and so on.

Thank you for reading.
