Install and launch your digital audio workstation. Programs such as Logic, Garage Band and ProTools allow users to edit, record and master audio using incorporated utilities. These programs are available for purchase through a majority of audio equipment retailers such as Musicians Friend and Guitar Center.
Create a new audio track within the workstation and import the audio you wish to master. The audio you have selected will appear as a waveform within the workstation. Carefully analyze the visual representation and look for any noticeable "spikes" in the wave. These eccentricities in the waveform will produce harsh or distorted sounds. Remedy this problem using a graphic equalizer.
Play the audio track and examine its sonic properties using the graphic equalizer. Depending on the program you are using, you may have to create and assign an equalizer to the track. Listen carefully to the quality of your audio as the "spiked" element of the waveform occurs. If you notice any abrasive high pitched sounds, reduce the upper-mid frequency range of the waveform within the equalizer. If the "spike" was created by excessive bass sounds, reduce the low-mid to low frequency ranges of the waveform. Refer to the documentation provided with your software in order to learn more about the equalization process.
Use a compressor to maximize the overall volume output of your audio. Compressors boost the signal strength of your overall production while limiting sounds that exceed a designated decibel range know as the "limit." Many commercial music producers make liberal use of the compressor in their productions. Websites such as TweakHeadz contain valuable information concerning proper usage of the compressor. Refer to the documentation provided with your software in order to better understand how to create and utilize a compressor.
Add reverb to an audio track to create a more authentic, "live" sound. Many digital audio workstations incorporate reverb processors that simulate a wide variety of physical spaces and reflective surfaces. Experiment with the reverb presets in your software to discover a configuration that enhances the quality of the music you will use in your DVD production.
