How reduce background noise while recording in iphone?
I am planning to compare two audio files. i have recorded two voices and compared them using cross correlation. since the presence on background noise while recording the resulting correlation value is always near 0.5.If i give any recorded waves from internet , i am able to get the correct value. So how can i reduce the background noise while recording.Please guide me .Thanks.
Is there any possibility to reduce noise from the recorded .wav file?

Not really a good way to remove background noise while recording other than simply turning down the recording mic. It seems that you're already exporting the data, so instead of attempting to eliminate it at the source, it'd probably be easier for you filter it out, this is a quick tutorial on how to eliminate background noise using Audacity
