Be sure to get an accurate track sheet and take log from the studio for each session. Monitoring and Mixing Bring along CDs that you are used to hearing on your home system and listen to them in the studio to get your ears used to how the studio's system sounds. As you get close to finishing each mix, check your mix against a CD of similar material to check your song's relative levels and sound. Check your mixes at moderate levels in your car or on a boom box. This is how most people will hear your music, so you want to make sure it sounds good on these types of systems.
Most mixes sound great when played at loud volumes on the studio's system.
But most people aren't going to hear it this way. Make sure your mixes sound good at lower levels on other systems. Don't try to mix right after a long tracking session. Your ears need time to rest and readjust. Take a day or two off and then come back in to do the mixing.
