Re: How to sound younger (like a child)

You can use G200KG Rovee or a similar plug-in to shift the male formants to female ones.
In order to sound like a girl, you have to firstly sing like a woman (how poetic...)

I'm not worth a penny when it comes to singing but anyways, here's an example:

Re: DTMF Decoder plugin

Why do you want to use FFT? It will become rather complicated. I would use the zero crossing rate as a pitch estimator. Alternatively you could use a filter bank in a similar way to how DTMF tones were originally decoded, for example along the lines of: [snip] Yes, originally, the decoding is made ...

Re: DTMF Decoder plugin

Why do you want to use FFT? It will become rather complicated. I would use the zero crossing rate as a pitch estimator. Divide the signal into two parts, one below and one above ~1100 Hz. The two Zcr (with a silence threshold applied) gives a low-sample rate signal (e.g. 2205 Hz). You can gather the...

Re: file won't go over 2GB

I work always with the newest alpha version and I've not encountered any fatal crashes or bugs.
It is certainly a bad idea to go back to an older version with e.g. an inferior resampling library.

Re: Fledgling voice artist seeking counsel.

Ahh, what a relief. There fit whole worlds inbetween those recordings. I think you're ready to go and to record the "real thing". There are some frequencies I would cut (remember the boominess I complained about weeks ago?). It is now really near to perfection and you might only notice the...

Re: Fledgling voice artist seeking counsel.

I guess, you are not performing Flamenco accompaniment as a rule? Your hand claps are what a Spanish would call "Sorda", i.e. dark. But we need a tight sound. This "Clara" is produced by clapping 3 or more fingers on the palm of the other hand. It is like praying but with one han...

Re: Fledgling voice artist seeking counsel.

A really stupid question, but are you sure you didn't record the internal Laptop mic instead of the Snowball? Firstly, it sounds exactly as with mine, device noise and all. Secondly, the forth example (extern) sounds as if you've recorded behind the door. My second guess would be that the audio come...

Re: Engine noise to components?

I would see Noise Removal as a spectral subtraction plug-in in its purest form The Noise Removal effect in Audacity is more of a "spectral gate" type of effect. Closely related to "Spectral Subtraction", except that the "subtraction" only occurs when higher level signa...

Re: Fledgling voice artist seeking counsel.

The impulse source hasn't to be in front of the microphone, for this purpose finger-snipping or the two pencils are enough. Louder claps should raher be made where the microphone catches least direct sound, i.e. behind it. Balloons and such things are better suited for large rooms such as a concert ...

Re: FeatReq: Notch filter 'invert+mix' check box

You could alternatively use the nyquist prompt:

Code: Select all

(diff s (notch2 s <Freq> <Q>))
you can also cascade the notches for an even sharper slope:

Code: Select all

(diff s (notch2 (notch2 s <Freq> <Q>) <Freq> <Q>))
