I'm looking to apply the A-weighting curve with a parametric EQ, using the standard filters and frequency, gain, Q/BW values. Minimum phase preferred, but linear is fine too. Does anyone know the correct values? (@jaakkopasanen ?) It doesn't have to be extremely precise, but let's say good...

The Apple USB-C dongle apparently has some trouble with very low frequencies, it produces some noise/distortion/clipping when playing such content. The problem is easily audible, but Amir's review didn't show it. So maybe adding something like this to the reviews would be useful. But I can't...

I'd like to match the levels of two amps with a multimeter, so that they both produce the same volume when using the same speakers. For my needs, testing with a simple test tone (like a 400Hz sine wave) is fine. Do I just measure the AC voltage from the speaker terminals? With a speaker load...

Is 44.1kHz fine as a delivery format and we don't need anything more? Just about the only objection from reasonable people I see is that it's hard to filter content in a DAC with that sample rate... Now, I only have a very superficial understanding of how a (modern) DAC works. From what I've...

As you may know, there are more and more people putting effort into measurements and EQ profiles for speakers and headphones. A user can then apply that EQ with something like EqualizerAPO. That's all fine and dandy.... unless you need ASIO and low latency. In that case, 3rd party solutions like...

I'm looking for a cheap amp to drive low impedance (32 Ohm) headphones. So I'd like to have low output impedance on the amp. I just need analog line in and headphone out. No DAC and no battery. A potentiometer is not even strictly necessary. Ideally it would be powered via USB, but I can live...

This is a review of the "BT200" Bluetooth NFC wireless receiver + USB player. The price starts at around $8.50 from the usual suppliers of gadgets from China. Features: - Bluetooth (5.0) receiver with RCA and TRS 3.5mm outputs - NFC sensor for pairing and quickly connecting/disconnecting a BT...
