I record my BIAB backing tracks as .WAV files (you could use high quality .MP3) and save them in a portable SONY player. Connect that to a house or portable PA system.
The key to selecting a portable player is the screen and user interface so you can find what you want easily, and control the transport.
I also record 20 seconds of silence at the end of each song, so I can control the player before it starts the next song by itself.
Thanks very much Matt. This is helpful.
So it seems getting the BIAB stuff into a .wav or .mp3 file is the best way to go?
It makes sense to me.
What player do you use, and are there any that you would recommend specifically?
I would have thought there would be many users who were performing with BIAB, but perhaps I was mistaken?
I wouldn't use it in a band situation, but for a solo gig, it would help fill things out for some songs.
I play guitar.
