  • Looking for suggestions

    What is the cheapest way to be able to measure speakers and save/output useful data (like fr and minimum phase in a .frd file)?

    Be real nice if it could use the imm6 (little cheap Dayton mic) as I already have it. (needs ability to input cal file).

    Even if it can't use the baby mic, what is my absolute cheapest option?

    I bought the imm6 and the basic version of audio tools for my iphone, which is nice to measure and look at for reference, but doesn't seem to be able to save and transfer .frd files; and the phase portion of the program is an extra $70+....

    thanks

    Win a FREE EMM-6 as a "door prize" (at a DIY event).
    Use ARTA for FR measurements (it's also free).
    Buy a "Blue Icicle" for about $35 (from some NYC camera store - shipping was included).
    (You CAN use the (6ft?) USB cable that comes w/the "cicle", foregoing the cost of a mic cable - JR does this.)
    Buy a WT3 on Cyber Monday for $69 (several years back).
    So, my measurement "system" ran me $104, and does F and Z files.

      Nice, exactly what I was wondering. Lucky score with the mic. Is the ARTA software relatively user friendly?

        Last time I checked, the free version of Arta will not let you save FRD files.

          Try HOLM Impulse. It is free and lets you save frd. There is a starter guide in the speaker building bible sticky.

            Incorrect Sir.

            The FREE ARTA does save out .frd files, w/ or w/out phase. It accepts mic cal files, lets you "gate", adjust mic levels, and does RTA as well. I THINK you can also measure impedance (for T/S parms and .zma files - but you might need to build that "jig" thing). The only thing the FREE ARTA won't do is to save "project" files (like the "for sale" version one will).

              Chris,

              I downloaded the free ARTA, but it says to save anything I need to buy a license. Is there a different version you have? Any suggestions as to what I need to do to get the free one to save? Here is the link of where I got it:
