In light of the contributions, I will be making all my headphone data available on public GitHub: HPDB - The Headphone Database project https://github.com/superbestaudiofriends/headphone-measurements I've thrown up a few files, so if you guys can test them, that would be great. I put up a bunch of files earlier only to realize that a few numbers toward the top of the frequency range got garbled (I wrote some code to normalize the frequency response files for their intended purposes). Note that with some headphones, I only have the result from one channel. One step at a time, so I want to start with frequency response first. This will be the most useful for people who want to create their own EQ profiles. The headphone frequency data I have put up there is compensated for a perceptual neutral as a straight vertical line across. For now, this data is copyrighted. However, can any of you guys who could tell me exactly what I need to do in concise steps to make it Creative Commons with Attribution? I don't care how the data is used, even if people want to make money from it with fancy EQ plug-ins. It would be great if someone can take the data and make a frequency response comparator. I'm too busy and most of my coding has been for tougher things involving numbers, e.g. attack and decay envelope for burst responses, etc. I know some of you guys have mentioned how you can help with coding stuff. Here is your opportunity. All measurement data will be compensated, but I will leave links with the reverse curves so that one can undo the compensation. I'm sure many will want to develop their own. Long term I plan on getting my legacy data from the flat plate coupler and "adapt" them to an SBAF comp. In some instances, I will provide both flat plate and miniDSP ears. For the sake of consistency, I will only provide compensated FR plots in a way which I feel best approximates perceptive neutral. Another reason for this is because the Harmon target is getting way too much traction by people who are smart but lack experience (Rtings, Oratory, etc). It's possible that the Harmon curve is indeed a curve that reflect consumer tastes, particularly with IEM uses in Asia*. However, I want a target that is similar to what sound engineers are accustomed to in the mixing and mastering studios near where I live in the LA basin. This will be a long term project, so feel free to suggest any ideas. Finally, any ideas on a brand name for this project? UPDATE: Use this tool to visualize the data: http://billp.site/projects/chart-tool/ Because 500 to 1500Hz is normalized to 0db in the data, yype 90 for the offset and press the "+" button next to the offset field so it displays properly. * Next time I hear someone say Harmon "neutral" target, I'm gonna rip someone's balls off.
