Data for new GRAS measurements are now being uploaded to the raw measurements database.
Added 2020-09-05 16:45:08 +0000 UTCAs you may already know, I've received the last few components for the GRAS 43AG-7 and will soon be going full-force into building up the headphone measurements database.
However, uploading and publishing the graphs themselves to a consistent format (with the watermarks of top crowdfunding contributors and all that) along with updating the Graph Comparison Tool to the new format will take some time, so I've uploaded the raw .mdat files (for Room EQ Wizard) to tide y'all over in the meantime.
Apart from FR, the .mdat data also contains some other (relevant) metrics that may interest you:
- Harmonic distortion breakdown (not reliable due to high noise floor)
- Impulse response
- Filtered IR (Schroeder Integral looks like something worth get into)
- RT60 (doesn't seem to differ too much from headphone headphone)
- Clarity graphs C50/C80 (also looks interesting, pretty large differences)
- Decay graphs in 20ms steps
- Waterfall/CSD/spectrograms
Thank you again for your continued support! Public graphs will (hopefully) be up by the end of the month.
