Re: Log sweep for testing using LSR3

You can send me the calibration file for conversion to the required wav format.

Re: Question before buying Acourate

Victor, I'm biased as I offer calibrated mics. Indeed I do the calibration against an Earthworks M50 mic as reference with a fully linearized speaker. The calibration result is dependent on the reference quality and on the applied measurement and mathematical evaluation. I do not claim to be an offi...

Re: Question before buying Acourate

The calibration looks like a 0° calibration.

But I do not like this zigzag curve. Green/brown is a comparison with a ECM8000 calibration with 0° + 90°.
A 90° calibration typically falls down already at 10 kHz

Re: Question before buying Acourate

Do not use the QX1002USB if you cannot definitely switch off the EQ section. Otherwise you will never find a reliable neutral behaviour. Colored measurements do not make any sense at all.

Re: miniDSP UMIK-1 - ASIO4ALL driver

Hello Victor, a calibration needs to be done against a reference. So the calibration quality depends on the reference quality. Of course the procedure has to be carried out carefully. This does not mean that you cannot do it by yourself. I just offer calibrated mics as many sellers do not take care ...

Re: Question before buying Acourate

Hi everyone, I have read a lot lately about the prowess of Acourate and the very nice job it can do with FIR filters for various players. Before I put my money in I need to make sure that the current setup I am running can be tamed with Acourate or if changes are necessary beforehand. I am running ...

Re: Macro 6 ?

David, 1. yes, your room is causing the observed effects 2. the pictures are equivalent. REW shows the phase in degrees whereas Acourate shows radians. 3. be aware that the magnitude and phase charts show a steady state. This means you see the phase differences with a long signal. But music is not s...

Re: Questions before getting started

Thanks for that explanation. I must say I'm a bit surprised that Acourate can only use one device at a time. Though perhaps there are technical reasons for it (possibly to do with measuring the delay between output vs input signals)? The terrific sound of my system depends on the quality of my dac ...

Re: LogSweep and Mic Alignment Error

1. My fault. By mistake I must have deleted today an important link in the internal playback chain. Please download the setup once again and install it over the existing installation. 2. You can use the resulting pulses from LSR3 recording 3. The picture of the recorded pulses seem to show up two pu...
