Select three or four of your best songs to record. To catch the attention of a record label, your demo should showcase only a small handful of your absolute best work.
Purchase or download a digital audio program with multitracking capabilities if you do not already have one. Popular examples include Logic, Pro-Tools, Cubase, FL Studio and GarageBand, as well as free programs like Audacity and Traverso.
Record each song one track at a time using your digital audio software. In other words, begin with a single instrument like a guitar, and then add a bass riff over it, followed by keyboards, percussion and finally vocals. To do this, simply designate a different track for each instrument and layer the different parts on top of one another. Your tracks will typically appear as long horizontal bars, stacked on top of one another across a time line in the browser of your digital audio program.
Edit each track individually. Your digital audio program will allow you to adjust all of the settings on each of your audio tracks, so make any necessary adjustments to make your mix sound as professional as possible. If certain tracks are too loud, soften them by dragging the volume slider downward. If your guitar tracks sound thin, use a distortion filter to add dimension. If your vocals sound hollow, add a touch of reverb. If your bass lacks punch, increase the bass level using an EQ filter.
Allow others to listen to your recordings and offer feedback. Since you have worked hard editing your music, you may miss some flaws that others will notice. Play the music for people who can offer a fresh perspective on the mix, and adjust your music accordingly. If you can afford it, you will benefit greatly by hiring a professional to mix and master your songs before you submit your demo to labels.
Design a CD cover for your demo. If you have graphic design experience, you can put together an impressive virtual image. If you excel at sketch art, you can draw a distinctive sign for your cover. You can also use a photograph that includes your name or the name of your band and any other visual effects that you want. A strong cover for your demo can go a long way in helping you stand out.
Burn your completed demo onto blank CDs and begin submitting to labels.
