    Measurement MacBook Pro Output (Newbie)

    hello, I want to measure my MacBook Pro headphone output with my ADI-2 Pro using the REW software. This is the first time I measure something and I'm a beginner.

    What mechanism is causing feedback in this setup?

    The other day, when performing near-field measurements of my study speakers (as part of designing a crossover for them), I started getting feedback when measuring close to the tweeter (Seas D2010/8513) with no test signal being generated. Measurement setup was: PC USB->Scarlett 2i2 audio...

    In IEMs - Is there a scientific proof that BA Timbre is a real thing? What about "Speed"?

    This whole topic is getting annoying. I don't need people to repeat the same facts about different technologies of drivers, Planar\BA\DD etc.. But can someone actually prove that there are differences beyond FR? An actual audible proof or something that impossible to refute? Debates about this...

    Behringer Truth B2031A - how truthful is it? (review / modding)

    I bought one speaker out of curiosity. I wanted to see the value the speaker delivers for just $199. What a great first impression unboxing and taking it apart! These things are designed (thanks, Genelec!) and built (thanks, Behringer!) really well: the cabinet is dense and solid, the driver...

    Audio Science review of Music ... any options or standards?

    Hi All, I'm new here - so let me know if this is wildly off topic or has already been dealt with. This site is messing with my head (re-educating me) about equipment; gone are my dreams of beautiful class-A valve monoblocks costing more than my car and instead I'm thinking about teeny little...

    Revel M16 - quasi-anechoic spinorama and misc measurements

    This is a quasi-anechoic spinorama measurement of the Revel M16 passive bookshelf speaker. Although this speaker was one of the relatively early ones measured in high precision using Klippel NFS in a review by @amirm (link), I figured it is always nice to have another independent data point so I...

    Apple Music iPhone EQ Measurements

    Has anyone ever attempted to measure the effects that the stock iPhone EQ’s have on frequency response? For people on the go, I think it would be super handy to know which frequencies the stock eq’s like Bass Boost, Bass Reduction, etc. boost and/or buck. Especially for people that are...

    Accuracy of phone base SPL meters?

    In another thread there was some discussion of matching levels for test tracks, and the topic of how to measure levels came up, so I tried a quick comparison. The phone was balanced on top of the UMIK, so it's mic was only about a centimetre away from the UMIK's capsule: In a quiet room I get...
