1. Make sure that all your tracks start at zero point and are synchronized with each other. You might need to create a region to export from in your DAW.
2. Generally, different types of tracks should be exported separately, i.e. clean and distorted guitars, different kinds of vocal, etc. Make sure that you’ve disabled all your effects and panning that you might have in your project before exporting. If you wish to keep your personal favorite effect, export a separate track with it enabled. Make sure there are no clicks or pops in your tracks, use crossfades while splitting, editing and consolidating them.
3. Mono tracks (most mic tracks, separate instrument tracks, etc.) should be exported as mono files. Export your stereo tracks (synths, bounced groups, special effects) as stereo files, accordingly. There is no benefit in exporting everything to stereo, as it just doubles the size of your files.
4. Bounce all your tracks to 24/32-bit WAV files, keeping your original project sample rate (44100/48000 kHz, etc.). Avoid upsampling, i.e. do not increase your sample rate after all tracks are recorded.
5. If you have a drum MIDI file, make sure that it is properly synchronized with the rest of your tracks and contains all necessary tempo information. Enable the “Embed Tempo” option (or similar) before exporting your MIDI file. Create a new project and import all your tracks, including the MIDI file, then check if everything plays as intended. Make sure you’re sending only correct and latest versions of your tracks. For some reasons, many bands stumble at this point.
6. Label all your tracks in a concise and clear manner. Specify the instrument type and its role (e.g. Rhythm Guitar Left, Snare TopMic, LeadVoc 1, etc.). If you’ve used multiple mics, it is a good idea to write that too (Lead Guitar 1 SM57). Do not include band name and song titles in track labels. Keep track naming consistent throughout your songs.
7. Create a text file with the tempo information (BPM), as well as your notes and ideas, so that I could grasp your vision and expectations. If possible, add your rough mix, as it can be extremely useful. Specify a number of commercially released songs as references.
8. Archive your material to a RAR or ZIP file and upload it to a decent file-sharing service (Dropbox, Google Drive, WeTransfer, etc.), then send me the link to mix your songs!
