Your hip~ at the end isn't needed if you've already got one at 50hz, <br>I'd be very cautious of trying to band pass just the fundamental tones of voice too, there's a lot of harmonics in the human voice, not to mention bits of 'noise' signal (like the 's' and 't' sounds) which need treble to be heard as language. I'd look for a compressor in PD to get a little more volume. Normalizing, by it's very nature, can't be done live, but a good compressor is a similar result (reducing the higher peaks then increasing the overall volume, Having said that, any ground sound from your microphone etc, might be increased by this approach, but it would by normalizing samples too.<br><br>Have a look to see if you can find a workable noise gate too, these cut a channel when the input drops below a given volume, often used for live vocals, so the gate opens when there's sound into a mic.<br><br><br><br>> Date: Thu, 27 May 2010 02:58:37 -0400<br>> From: puredata@11h11.com<br>> To: pd-list@iem.at<br>> Subject: [PD] microphone cleaner advice<br>> <br>> hi everyone,<br>> <br>> i would like to clean a signal coming from a noisy microphone.<br>> <br>> what i have in mind right now:<br>> <br>> remove low-frequency noise below 50 Hz<br>> bandpass filter (for voice *)<br>> global amplitude scaling (realtime normalizer?)<br>> limiter~<br>> hip~ 5 (remove dc)<br>> <br>> * The voiced speech of a typical adult male will have a fundamental <br>> frequency from 85 to 180 Hz, and that of a typical adult female from 165 <br>> to 255 Hz<br>> <br>> any advice is welcome (also patchs and externals).<br>> pat<br>> <br>> _______________________________________________<br>> Pd-list@iem.at mailing list<br>> UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list<br> <br /><hr />Get a new e-mail account with Hotmail - Free. <a href='http://clk.atdmt.com/UKM/go/197222280/direct/01/' target='_new'>Sign-up now.</a></body>
