Audio “quality” is a very subjective subject. There are so many variables at play to simply say that a higher bitrate audio file “sounds better” than a lower bitrate one. What sounds good to me may not sound good to you, even if it is played back through the same player, in the same room, and through the same speakers for both you and I. To some extent you can reduce some aspects that influence the sound, such as the size of and furnishings in a room and the resultant …

Hey Guys… I think it is difficult to tell for someone listening through home speakers or car stereos… or even a pair of very good consumer grade headphones. But as a DJ… the difference is astronomical when you play it in a venue through a loud system. The difference is even more astonishing when you play through a system that is EQ’ed properly and has speakers and acoustics with a wide range of frequency responses.
I’ve made the mistake of playing a set with a couple of MP3s mixed into a …

Mosquito ringtones emit high-frequency tones that are inaudible by adults but can be heard by teenagers. It is very normal for people to lose their hearing as they age. The loss of hearing is gradual in most people, while other may experience more severe hearing loss.
The high-frequency tones (or mosquito ringtones) are those above 17kHz. Most people over the age of 30 will not be able to hear them. Below are file downloads in MP3, WAV for windows based phones, OGG (Ogg Vorbis audio format), and M4R (iPhone …

I heard a difference between the mp3 and wave versions, except I hated the wave version! I found it to be -worse- than the mp3. It was [cold], its musical life had been [erased] somehow. I would certainly not create a master from -this- version for pressing. It does not produce the same harmonics as the mp3 versions I downloaded (yes, plural. Long story short, I ended up comparing 4 copies of the mp3 vs. 1 of the wav. file). I suggest something in the conditions was different when the …

I’m 53, an ex-sound engineer. Got really over exposed to loud sounds during the rave scene in the UK during the 90′s. I have bad tinnitus in both ears & a high frequency loss in my right ear. I can hear the fundamentals up to the 12Khz ok, but my cheap sound card gives audible harmonics for many of the higher samples. (I obviously would not have been able to hear the true tones even on good equipment in a perfect anechoic chamber) Great site! & take it from me …
