Amazon's player is on Apple, PC, Android so that's a huge chunk of the market.
I have written a language textbook that includes a CD. How can I put the audio files online for digital download?
The textbook currently includes a CD. However, I would like put the audio files online to be accessed by those who have purchased the textbook. Is there a way to have a download code with each book or something like this? Is there a company that someone can put me in touch with? Thanks!
