Hello, I just did a simple audio experiment and it failed... if you could comment on it and/or suggest some changes to make it work: i have a walkman which is in very good condition. the output sound quality of hte walkman is excellent. i connected the output of the walkman to the computer mic socket using a simple audio sterio cord and recorded the sound using sound forge in a .wav file. Now, when i playback the recorded audio it is distorted and of very bad quality... What could be the reasons? (is it impedance marching or is it sampling rate or is it that audio can not be simply recorded to .wav format or what?) What changes would you suggest to make this simple experiment work better? regards, APS

Hello salaria, computer mic socket has a hidden "amplification button". In windows XP you can go to the Sound mixer press Options->"More Options" And on Microphone "More". There's a mircrophone amplifier, depress it, it sounds that your signal is too great for the input. Regards, Wolfgang

You need the line input after using the right settings on control panel. F.

Hello Wolfgang, In the recording software which i was using(Sony Sound Forge), there is an indicator which indicates the level of input sound and warns(colour changes to red) if the sound amplitude is going above the recording threshold. It clips the input if it is above threshold. I tried recording at very low volume, still the recorded audio is very bad. I do not think that could be the reason.. I will try to check the recorded signal with the change you have suggested. Thanks!, APS>Hello salaria, > >computer mic socket has a hidden "amplification button". >In windows XP you can go to the Sound mixer press Options->"MoreOptions">And on Microphone "More".

Send your signal to the "line in" connector if your sound card has one. If not, use an external attenuator about 100:1. Use the Walkman's "line out" port instead of the headphone output.
