Restoration is the process of improving audio quality by removing unwanted noise and/or processing the audio with sonic enhancements.
Many of the software tools we have at Polkasound are specifically designed for improving and restoring audio quality. Four of the key software tools we use for audio restoration are:
We want to emphasize that recorded music can only be restored or improved to a point, simply because an audio recording cannot be broken down into its individual parts. The best analogy to explain this is paint. Once you mix several colors of paint together, you can't un-mix them. Once you mix eggs, milk, and butter together, you can't un-mix them. The same is true for recorded audio. Once you mix instruments, vocals, and even background noise together, you can't un-mix them.
What restoration software does is process the frequency ranges where specific instruments or noises are found in the audio spectrum. For example, if an accordion is too shrill on a recording, we'll find the frequency range where the shrillness exists and subdue it as needed. It is impossible, however, to physically isolate the accordion from the rest of the audio and adjust its level or tone without affecting the other instruments in its frequency range.
With our high-quality mastering software and years of engineering skills combined, significant improvements to a recording may be possible, but limitations do exist. If instruments or vocals need to be individually processed or adjusted, then remixing the music from the studio multi-track recording would be required. If you're not sure to what extent your project can be restored, please contact us for a free consultation.
