Re: Need help with G.711 8 khz 8 bit mono u-law wav file

You may be in the wrong Audacity. You can get Audacity 2.1.3 from here and then install the FFMpeg add-on software (scroll down). http://www.audacityteam.org/download/windows/ When you get that far, File > Export Audio > File Type: Custom FFMpeg Export > Open Custom FFMpeg Export Options. I see G722...

Re: Waveforms Disappear After Noise Reduction

Obviously, if you're a southpaw, you might want to put the microphone on the right. I'm a northpaw.

Re: Waveforms Disappear After Noise Reduction

This is our friend David Greene with two different microphones and about the right spacing for both. He's using pop and blast filters for both because when you get closer, you have a risk of popping your P sounds. I can't find it immediately, but somewhere here is a suggestion document how to pile u...

Re: Waveforms Disappear After Noise Reduction

How far away from the microphone are you during performance? You should be somewhere between Power Fist and Hawaiian Shaka (attached). Your first voice during the scratch test is almost perfect. Your voice during the test clip performance is very low which almost without question is causing the nois...

Re: Waveforms Disappear After Noise Reduction

Do you know where the microphone on your laptop is? Mine is behind a grill just to the left of the left-hand shift key. The laptop before this one was actually on the lid behind a little hole. Something Is Very Wrong. Let's do a scratch test. Start recording and say "this is the microphone"...

Re: Waveforms Disappear After Noise Reduction

Well, I knew that much... You'd be surprised how common it is to find people speaking into the end of the cylinder like a rock-band microphone instead of the side. We have a pretty good idea what the front and back of the microphone sound like, but the top is undefined territory. (behind and undern...

Re: Audacity forum test clip

http://forum.audacityteam.org/viewtopic.php?p=301128#p301128 Some caution here. The hardware, microphone and soundproofing notes are valid, but the AudioBook Mastering Suite 4 has only been on-line since about the middle of June. Any projects posted before then are using the old system for sound cor...

Re: Issue with Audio Interface. (U-Phoria UMC202HD)

Audacity has had problems with managing stereo USB adapters in a mono show (as you found) and further, even if we had good techniques of converting in real time, there's no way to get the sound back out to you without machine latency. There's always an echo in the sound and past recompiling the Auda...

Re: Am I Doing This Right?

A side note to the side note: they're all taken up with human breathing. Do Not go in and carefully excise all the breaths. ACX expects normal humans to be reading this stuff and normal humans breathe. Given if you have verbal ticks or other annoying noises (holding up hand), then yes, you might nee...

Re: Am I Doing This Right?

processed room silence I believe that. We can't use the spaces between words because they're all taken up with human breathing. That stupid 20 second voice test is harder than it looks. I Expect that first two seconds to have some noise in the -60dB to -70dB range. What kind of noise depends on a m...
