![]() ![]() ![]() (might do it for some thig at one time) so wondering is this able to make entire songs or do I need some other software. Headphones are optimally suited for analyzing tonal artifacts in a recording but completely distort distance perception.Цитата допису eidane:I want to start making music. "Headphones are completely unsuited for judging the spatial rendering of a stereo recording that is intended for loudspeaker playback. Headphones are optimally suited for analyzing tonal artifacts in a recording but completely distort distance perception." -LINKWITZ Money doesn't buy pleasure ever."-Alan Watts "It's enormously important to understand that there is absolutely no possibility of having any pleasure in life at all without skill. Unfortunately very few of our current genre of acoustic tests have had this kind of introspection." - Geddes It is the perceived sound quality that matters not the measured quality – unless that measurement has been scaled and correlated to subjective perception through valid psychoacoustic tests. "Blind reliance on measurements can be misleading ‐ one needs to tie those measurements back to subjective perception. The room response gives a picture of the steady state SPL, where sound generation and sound dissipation in the room have reached their equilibrium." -Linkwitz The resulting curves must not be taken as a 1:1 representation of what is heard as loudness at different frequencies. " The room response must be averaged to recognize trends in the summation of direct and reflected signals at the microphone. I guess it is possible this one speaker sample has an issue in which case I encourage Elac to try to replicate this problem and let us know what is going on.įor now, I can not recommend the Elac Uni-Fi 2.0.Īs always, questions, comments, recommendations, etc. FYI Eva Cassidy album is standard issue at all audio shows in multiple suites so it is not like it is some oddball track one never sees. Given how easy it was to detect the issue in multiple measurements, it should have been caught and fixed.Īs far as I am concerned, this is a show-stopper, broken design. And in a design from the talented Andrew Jones. They don't become instruments on their own. What a shock to discover what I did with this speaker. As a confirmation, I played the same track on Revel M105 and it sounded wonderful with zero issue (I have used the same track to test at least 100 speakers). This so called spinorama shows us just about everything we need to know about the speaker with respect to tonality and some flaws: ![]() Likewise listening tests are performed per research that shows mono listening is much more revealing of differences between speakers than stereo or multichannel.Īcoustic measurements can be grouped in a way that can be perceptually analyzed to determine how good a speaker is and how it can be used in a room. Measurements are compliant with latest speaker research into what can predict the speaker preference and is standardized in CEA/CTA-2034 ANSI specifications. Measurement location is at sea level so you compute the pressure. I performed over 1000 measurement which resulted in error rate of less than 1% through majority of audible band. In a nutshell, the measurements show the actual sound coming out of the speaker independent of the room. Both of these factors enable testing in ordinary rooms yet results that can be more accurate than an anechoic chamber. It also measures the speaker at close distance ("near-field") which sharply reduces the impact of room noise. This is a robotic measurement system that analyzes the speaker all around and is able (using advanced mathematics and dual scan) to subtract room reflections (so where I measure it doesn't matter). ![]() Measurements that you are about to see were performed using the Klippel Near-field Scanner (NFS). ![]()
