![]() Note also that the difference between QT Player and Audacity in both cases is very small (☐.1 dB), whereas the difference between those two and Amadeus Pro in both cases is around 6 dB. Note that the peaks in the two preamps differ because I wasn't trying to get them to be the same as each other - the point was that, for each preamp individually, the gain levels were not touched between recordings. Audacity (saved as FLAC, highest-quality settings) -4.6 dB I used AP's Waveform Statistics to determine the peak amplitude for each file.Ĭode: Select all - QuickTime Player (max recording quality) Peak Amplitude -4.5 dB I'm using AP 2.1.7 from the website because the MAS version isn't working right now. When using an external preamp, the gain is no longer alterable from within Amadeus Pro, so that's not a variable either. I did a set of recordings for each piece of software using two different preamps (Onyx Blackjack and Focusrite Scarlett 2i2), to rule out the preamp as the source of the problem. I recorded all the samples with the same 3 pieces of software (AP, QuickTime Player, and Audacity). I created a brand-new user profile so that the settings of each app would be on their defaults (to protect against my having changed a setting and thus having caused the problem myself). I set the ringtone to my recorded text and simply called myself from another phone to play the ringtone. The phone was placed on a music stand in front of the mic and was not touched at all during the tests. The sound quality of that recording is terrible, but it was consistent across test recordings, which was my goal. This was to ensure that the audio being produced for the mic in the booth would be the same every time. I recorded myself reading some text on my iPhone. However, to further protect against variability: (I've also tested the mic on a friend's setup, and it sounded great, so I know the mic's ok.) with the same mic, preamp, and gain settings To make the test valid, I wanted to eliminate as many variables as possible. To make a rather long story short, I have devised some tests and found that, with the same preamp and gain settings, I get exactly the sort of sound you would expect when I use other software, but not when I use AP.īelow is the recording test I did to prove this to myself. What I basically was able to narrow this down to, as a measurable difference, was that the peaks in AP are lower than they are in other software. My problem has been that my recordings are too quiet, and when I increase the gain on the preamp to get (almost) acceptable peak levels, the background noise is rather horrid. Obviously, it is entirely possible that I'm just not understanding something, but please read about my tests and let me know if you think I'm insane. It seems, however, that the problem is originating in Amadeus Pro (AP), so far as I can tell. Hi, all - I've been struggling with this problem for about a year, and all this time I thought that the problem was my preamp.
