What I Do When Key Change is More than a Whole Step This will let you transpose into any key right in Planning Center. Now, hover over the MP3 file name, click the music icon. Upload the original MP3, attaching it to the original key. Simply click the song, then the arrangement. If you are using Planning Center Online, this can be done right within the song. Give it a few minutes and then your new transposed MP3 will be ready for download. Upload your MP3, choose the original key and new key, then click ‘Transpose Now’. Open Planning Center’s Transposr tool by visiting. Although this is a paid app, I find it well worth the few dollars it costs. So, to use the MP3 transposing tool, you first have to convert the track to an MP3. Technology has moved beyond MP3s and into higher quality audio using M4A or AAC format. When you buy music, it rarely comes in MP3 format. If you need to go beyond a whole step, this tool will do it, but it ends up sounding rather odd. Maybe the lead vocal can’t quite sing as high as the original, or the original is in a weird key (such as Ab). Generally, I only change the key a half or whole step. After all, how would the musicians practice along with the track on their own? Then, I discovered a free tool that will transpose (change the key) of MP3s. (While it's true that I could also open them in just about any audio editing program like Sound Forge or Audacity (which I have), the advantage that a DAW has is that processes like this can be non-destructive)I used to be afraid to deviate from the original key. Whenever I need to perform this not uncommon task, I feel frustrated that I can't utilize them more fully. The algorithms that would do the signal processing are already built in to Cakewalk. I would like to be able to apply finer increments of pitch shift via the Process/Transpose command (and/or right click on the clip). We have the Process/Transpose command, which can be applied to clips from the global menu, but it only allows shifting pitch in half-step increments, which is of no use when someone shows up with something that's say, 5 cents flat. This process is buried very deep in the Reference Guide and took me a long time to find. If I get a file from someone that's recorded just a few cents sharp or flat in pitch, the only way to remedy this using Cakewalk (and not with an expired trial of Melodyne) is to open the file in Loop Construction View.
