The target traces made available here are the product of more than a decade of trial and error.

Over the years, these .trf files have been publicly circulated across the industry and have since come to critical acclaim such that they are being sought out by industry peers and audio experts the world over.

On occasion these have even been re-branded and modified along the way. Subsequent to this unattributed remix-culture, we’ve decided to make the originals available from a known source.

Non-Summed Main & Sub targets have been made available for users which require more or less spectral tilt, but you will find that the Summed target works nicely for most genres of music. Please remember that you must adjust your spectral tilt to taste in each use case…

These .trf files are made available here at no cost, for use as-is, commercial use is approved with attribution, and we make no claims or statements of any kind regarding the results you might have if you utilize these files in any way.

Special thanks to our friends at Rational Acoustics, creators of SMAART; as without their products and decades of dedicated research & development we wouldn’t have anything to share.
