Proscan - SDS200 - Notch Filter Range?

[brumey]

As other threads have stated, on some P25 systems and some operators, I get a very bassy audio which makes it difficult for me to understand. I read a few threads referring to ProScan's Notch Filters and I found the options today. It looks like that options is to filter out a specific frequency and not a range. I was hoping to find a way to filter say everything from my internet Proscan Webserver audio under 300hz or a range say 50hz - 300hz.

Can this be done and I am just not seeing the options in Proscan?

Thanks....

Audio below 300 Hz is usually filtered out of 2-way radios and scanners. Otherwise, you would be hearing CTCSS tones.

I don't know if you can reduce the annoying nasal sound, especially coming from P2 or DMR systems.

I've had noise ride in on audio cables from scanner to computer. Using the Audio scope I was able to knock down frequency specific noise frequency, and high CTCSS tones 250.3. 60cycle noise. The notch is not very wide, like a few hz, multiple notches every few hz in the noise helped me.
On another system the fire department has a 1000hz alert tone that blasts at 0 dB, put a notch that, also good for knocking down paging tones, or the brown notes 333, 666 LOL

Only in analog. Unidens scanners only apply a highpass filter of 250Hz to the audio from analog transmissions and digital audio are unfiltered and bassy, a mistake by Uniden I would say. Most digital system use no EQ filters for their audio and bass frequencies are then way too dominating and overloads both audio circuits and microphones and speakers and the important higher frequencies are disappearing in AGC circuits and in audio limiters.

Can anyone suggest good notch filter Hz values for Fire/EMS toneouts to enter into RadioFeed for my BCFY feed ?

Best way I found to do this is with an audio spectrum anayzer app on my phone.
