Re: Noise removal help from my voice recordings

Slight improvement on the last post. Use the following code in step 3 (also removes 57 Hz hum) (notch2 (notch2 (notch2 (notch2 (notch2 (notch2 (notch2 (hp s 20) 57 10) 210 20) 420 20) 629 30) 839 40) 1048 50) 1257 60) In step 4, the Noise Removal settings can then be softened: Noise Reduction: 20 Se...

Re: Noise removal help from my voice recordings

You're asking for miracles. The noise level is very high, the recording level is too high and has caused clipping to occur, there is significant DC offset and the sample rate is a bit too low. I would guess that most of the noise is produced by the sound card, which I guess is the built-in sound car...

Re: Sudden failure to record

I have always been able make Audacity recordings from phono - LP and directly from internet, both through "Line In" How did you make recordings from the Internet through "Line in"? Do you use a "loopback connector" (an audio lead connecting the line out socket to the l...

Re: Sudden failure to record

Don't bother with Audacity 1.2.6, it has several bugs that have appeared since it's release, but they won't be fixed because all work is on Audacity 1.3.x toward the release of Audacity 2.0.

Is the microphone OK? Have you tried recording from anything other than the microphone?

Re: Not-well-formed (invalid token) errors with .aup files

But the bugs from above happen with Unicode as well as with ISO-8859-1 encoded .aup-files. When I downloaded the files, GEdit says that they are all ISO-8859 encoded. Why would a Unicode build of Audacity encode the AUP file that way, or is the encoding being changed due to uploading/downloading to...

Re: Noise with very low sound music

* you could try "exporting" (saving) your Audacity files in 32-bit depth WAV format to avoid this constant but minute noise, if you've got plenty memory. That is the ONLY way to avoid adding distortion and/or noise. After amplifying the audio down by 28 dB or so, 16-bit formats do not hav...

Re: Not-well-formed (invalid token) errors with .aup files

There was a case that came up recently where an Audacity Project had been made using an ANSI build which would then not open on an (updated) Unicode build. The problem was that the AUP file contained extended ASCII characters (if I recall correctly it was an umlaut) that are not in the Unicode chara...

Re: Noise with very low sound music

What I mean is that I hear no more noise (in absolute terms) on the "Low level" version than I hear on "Original" version. If anything there's slightly more hiss on the "Original" version, but it's mostly masked by the sound of the music.

Re: preference of the silence maker

There's a couple of approaches that you can take. I'll give the steps of how I do it, but I'm not sure that they will work on Audacity 1.2.x as I am using Audacity 1.3.13. I would highly recommend upgrading to Audacity 1.3.13 as it is a lot more functional than the old 1.2.6 version. Also, 1.2.6 is ...

Re: Physically how many sounds can be played simultaneously?

I thought it might be something like that. I presume that each of your "sounds" would be pre-recorded audio data and your program would trigger the playback of the appropriate audio sample at the appropriate time. So in a "busy" part of the game, there will be a lot of samples pl...
