Condition monitoring audio samples search

[sevana]

Hello,

I have a tool to compare two audio files, and would like to make the following test:

1. have an audio file with sound of new fully funcitoning device (a gear, an engine, etc)

2. have an audio file with sound of the same device with some technical problems or older (the same gear lacking lubrication, engine with some internal problems)

Then I would like to compare these two files and basically get an answer if this tool can be used in condition monitoring in a way or other, but I am absolutely lost searching for such audio samples. I would be very thankful if somebody could give me some of their own audio of that kind for testing purposes or point me to an Internet resource to download that kind of sounds.

Thank you very much in advance!

Best regards,

Endre

HI sevana

Is your files in wave format? Labview is able to read wav files. You will find some examples in this folder labview\examples\sound2\sound2.llb. I guess you can take if from there. These functions is in Labview base. As analysis I think a "Time frequency analysis" would be useful.

Ps IF your files is not in wav format, they may be converted. Soundcards are often delivered with such software.
