OK thanks I was thinking they should have all been the same.... Just as a note - EAC : Wav Compare is pretty good at giving these differences, it will tell you any spots where there are different samples to .000 of a sec, and it says the whole files are different...., I know you could not hear a few...

So that tells me it has to be something to do with the older and newer version of Audacity when making the speed change.... Why do you expect two different versions of Audacity to produce "bit identical" results? Those two versions may (will?) each have been built using different versions of the co...

Have I got this right: You have two RAW files - one is the original and one has had the speed changed. If you now change the speed of the original file, the result is different from the one that you made two years ago? How much different is it? Does it sound different? How can you be sure that you ...

I can't figure it out.... I have a disc with the raw unedited files, and a disc with the speed changed files... The disc with the speed changed files has 1 file which has not been speed changed, and the samples of that match with the samples on the disc with the raw data.... So that tells me it has ...

How many audio channels?

Hello, I'm using Windows 7 Pro 64bit and Audacity 2 (19.8MB), I have previously been using an Audacity version from around 2009/2010. I have a raw .wav file I did some speed changes on back in 2010, when making the same speed change to the same raw file with this new Audacity and comparing in EAC .w...

Hi, (using Windows 7 Pro 64bit and Audacity 2 19.8MB). I have been using a version of Audacity the past couple of years, and when making speed changes to a file the samples would stay the same, eg. if changed the speed of the same file twice and compared each of the 2 output files in EAC WAV compar...

Thanks everyone, yeah I chose to use my installed audio drivers rather than have Windows select whatever....

Thanks, for volume/speakers do I use "Primary Sound Driver" or "Realtek High Definition"?
And for microphone I have options of "Primary Sound Capture Drive" or "stereo mix - Realtek High Definition"?
I think I probably should go with the "Realtek High def" options?
