PowerGramo

Hello,
I have used Power Gramo (paid version) to create about 10 podcasts by now, an example of which can be listened to at this URL:

If you listen to the first minute or so, I think you will notice that the recording becomes disjunct, and contains many artifacts. These issues happen when recording the "In" and "Out" voices onto dual tracks. The problem happens in both .ogg and .wav formats.

To help solve these problems, I have a few suggestions:

A) Make the sampling rates adjustable from 11 kHz up to 48 kHz, with a pull-down menu. You can default to 44.1 kHz or 48 kHz, but being stuck on 48 kHz may be a little rough on the CPU -- I use a Win 2000 dual CPU at around 2 GHz.

B) A software-compression option -- this would help avoid the incoming or outgoing signals from overloading (squaring). Compression does eat up CPU, so this might be an option that defaults to "off". If compression is too much of a bother, then a limiter circuit would be fine (for example, at -6db).

C) Have independent "gain" adjustments for "In" and "Out" voices. The signals coming in/ going out of Skype are rarely the same. I have noticed that my outgoing voice tends to be recorded at better quality than the voice I receive. So far, I am saving each mono track to separate WAV files and independently normalizing them before importing to ACID 5.0, but I need to tweak the levels a lot in ACID to even them out.

I have a listenership in Tokyo numbering in the 1000s, so if PowerGramo can be adjusted to fill these needs, I think it will invite more sales.

Thanks for your consideration.
