Audacity Forum

I see what you mean. I couldn't hear it until I turned up the volume quite a bit, but it's certainly there. I'm not crazy, or I'm not alone! Thanks for testing this out. So, if Audacity's Project Rate is set to 44100 and the default format is 48000, the system will have to resample the data Audacit...

Here's an update: I restored the hard disk image that was on my Vista PC the day I received it from Dell (Summer '08). With that image, and nothing new installed but Audacity 1.3.6, the playback issue was still observed. So, it would seem that the PC arrived in this condition.

Vista x86 (Home Premium) Brand new PC... just 5 weeks old. Intel Q6600 Quad Core with 4 GB of RAM. Over a TB of disk space. That's a sweet sounding rig. Anyway, I did try exporting to mp3 (single tracks, and multiple tracks) in 1.2.6 and in 1.3.6 and it never failed. I have Lame v3.97 and used a bi...

Look, a Vista user!! This isn't Vista64, right? I've exported MP3s using 1.2.6 on Vista32 (home premium)....but it's been a while, so I'll try it again when I get home tonight and report back just to be sure. I'll also give it a shot on 1.3.6. If you have time, I'd appreciate it if you'd try this Vi...

I suppose it's "possible" the new Vista audio stack has problems we don't know about yet, though if there have been playback or recording problems in the past with Audacity on Vista, switching from 1.2.6 to 1.3.6 has tended to cure them. The switch to 1.3.6 does not help in this case, just to be cl...

Using Vista, Audacity playback is colored when the Audacity "Project Rate" is not equal to the default sample rate of the playback device (called the "Default Format" in Vista). This coloring can be demonstrated on any Vista system. Here's how: 1. Set the Default Format of the playback device to 44...

So why the distinct double peak, Because the main lobe has no energy at or around 0Hz. and why not on my computer? From all observations so far, this appears to be a Vista+Audacity thing. Is this with any version of Vista? Vista Home Premium, on both computers. Is this with dual processor machines?...

I've isolated the distortion Vista_SB_MP3_resample_noise.ogg.zip and it appears to be two frequencies, one at around 3800 Hz and the other around 4000 Hz "chirping" along with your bass notes. And here's the plot of http://webpages.charter.net/friedl/Vista_SB_MP3+_playback.wav : http://webpages.cha...

Steve, I tried Real-time Fast/None on 3 different sound cards to no effect. In fact, there is nothing I can do with the real-time settings to change the sound, unless I change the project rate to something different than the rate of my tracks - that's where I start hearing a difference between Real-...

You should have the real-time SRC Fast Sinc Interpolation and Dither = none. I'll try this when I get home, but my experience leads to me to believe the real-time SRC is only used if the track sample rate is different than the project rate. Your quote here: The data that Audacity sends to the sound...
