Hi, I'm hoping that someone will help me get a backing track adapted for a carol service on Monday. Am trying to transfer a track and transpose it down a tone, but when I import the track and play it it is only 2 seconds or so long and an earpiercing shriek. Anyone any ideas where I'm going wrong? Have seen a students of mine do it but can't work it out. Am also going to post this in music.
What is the format of the backing track? How does its filename end? In a '.wav' or a '.mp3' or a '.mid' or something similar. If it's a '.mid', then it's a MIDI file. Rather than actually record the soundwaves, this file simply tells an electronic instrument or synthesiser to play a group of notes (effectively it says "play middle C, then wait, then play D" etc).
If Audacity doesn't realise that this MIDI file is a list of instructions, but tries to play it back as a soundwave itself, then I you'd just get garbled rubbish.
To play back and transpose a MIDI file, you need a MIDI sequencing program, which understands the lists of instructions and is able to create the notes on demand. You can get a number of these - are you on a Mac or PC?
Hi! just to let you know, I worked it out!! Service was great, choir sang really well and the backing track worked a treat. Just needed to convert the track to a wav file on the preferences (I think!) area.
