Hello,
I am a musician, instrumentalist, audio editor, to mix-mastering. Academically, I am an ethnomusicology scholar at the Indonesian Institute of Arts in Yogyakarta.
This week I am not very busy, only a few people are jingle-bumper-song for radio stations. So, I will be able to maximize my time for the work you offer.
If you need to, I can submit a sample to you, according to the audio you want to work on. No need to pay for samples. This is my daily job, so I think it will be very easy for me. Please communicate if you are interested.
* In the meantime, the time I can say for work is 1 day (even if only a few hours). but if you find that your audio is very large, I will need more time than that.
