Japanese Volume Lessons a bit low

I have to turn the volume on my computer quite high to hear the speaker clearly. So far it seems to be all the Greetings and Goodbyes Japanese lessons Part 1 to Part 6.

Is there a way for me to adjust the volume in lesson?

Hi vinfang,
Unfortunately you can’t adjust the volume manually, but we’ll do our best to re-upload audio files in lessons you mentioned. Thanks.
