Every curve file here is exactly as published, unchanged. Each download is a small zip: unzip it, then load the file in Dirac Live. These are the same curves Dirac links to from its own target curve guide.

Harman curves
Three versions with +4, +6 and +8 dB of bass lift, based on Harman’s listening research. Punchy and dynamic, and a good starting point for films.
- Harman-4dB.targetcurve
- Harman-6dB.targetcurve
- Harman-8dB.targetcurve
Audio Advice curves
Three versions with +3, +4 and +5 dB of bass lift, from US installer Audio Advice. Audio Advice recommends starting with +4 dB and moving up or down to taste.

- AudioAdvice_4db_bass_gain.targetcurve
- AudioAdvice_5db_bass_gain.targetcurve
StormAudio cinema curves
Three curves, one for each speaker type: left, centre and right; surrounds; and subwoofers. Designed for dedicated cinema rooms played at high volume.
- LCR Cinema Target StormAudio_.targetcurve
- Surround Cinema Target StormAudio.targetcurve
- Subwoofer Cinema StormAudio.targetcurve
NAD curve
A warm curve aimed at stereo music, generated by Dirac Live for NAD. It comes as a .txt file, exactly as published.
- DiracLiveFull_NADTargetCurve.txt
Flat curve
A straight 0 dB line. Useful as a reference to compare other curves against, rather than for everyday listening.
- Flat Curve.targetcurve
All files are credited to their original publishers: Harman research, Audio Advice, StormAudio and NAD. We haven’t edited them. If a curve doesn’t suit your speakers, adjust it in Dirac Live after loading rather than editing the file.
