Most audio (wave) edit programs offer that feature.
Search for wave editor.
Goldwave, etc. I use CoolEdit v1.2.
Do u mean i need to add a power amplifier to the sound card? Im currently observing the output via the bluetooth headset from my mobile phone not via the sound cardA simple power amp attached to a sound card output just about any sine wave you want, but no DC offset, sound cards outputs are nigh universally capacitor decoupled.
But im not observing the output from my soundcard. First, the tune is sent to my mobile phone and when the tone is played from my mobile phone the output is observed via the bluetooth headsetThe sound card will only directly output about 2V peek to peek directly, and VERY little power. You need an amplifier to get more than that, a decent set of PC speaker amplifiers would do.
Im currently doing a project for my final year . I see. Thanks for the advice. So i need an amplifier at the output of the headset right?The output of a bluetooth headset is probably at most puting out a couple of volts. You'd need to amplifier it from the bluetooth headset. What is the point of all this?
