How much quality of a microphone do you need for simple measurements
Simple measurements can tell you something How much quality of a microphone do you need for simple measurements? As David explained in his last blog simple distortion measurements. It is of course possible to extract relevant insights […]
Simple Distortion Measurements
Do simple distortion measurements make any sense? Even if taken from loudspeaker output? With simple, non-laboratory grade test instruments and environment: can we read anything interesting out of distortion measurements? I made some, using REW […]
Flaws in audio at listening position – phase coherence or polarity variation
Theory explanation I found the explanation of Jeff Towne: Its a phase youre going through quite understandable, therefore I refer excerpts including a listening example of it here. It’s a perplexing problem: the mystery of […]
Some new HiFi adventures
A Re-Visit Back to a friend and customer’s place I had a strange experience which I would like to share. And still don’t quite understand … The System is complex and very high quality : […]
Flaws in audio at listening position – stereo channel time coherence
Theory explanation Stereo, a method of sound reproduction We described stereo effects to some extend already in the criteria stereo capability and Frequency response channel correlation. Stereo is a method of sound reproduction that […]
Woofer Size
Why woofers need to be large to radiate efficiently Due to a recent discussion about efficiency and directivity: Is higher efficiency – like with horn systems – a result of higher directivity? Produced by restricting […]
Flaws in audio at listening position – frequency group time coherence
Theory explanation Time and phase coherence is a very complex topic, probably not yet fully researched which and how those issues directly influence or correlate to the subjective perceived sound quality. However, it is […]
Why isn’t time and phase a prominent topic in audio?
Stereo channel time and phase coherence Sound mixer or sound engineer proactively design the sound with in-phase or out-of-phase channels. More mono able sound, i.e. channels in-phase will sum-up in levels. Amplitudes of same frequencies […]
Time and phase coherence – live, MQA, playback, overall
This is a very complex topic. It is not fully researched which and how the issues directly influence or correlate to the subjective perceived sound quality. However the overall time and phase coherence influences the […]
