Hi @eritter - Eloy
We've made note of your request and I'd like to explore this in more detail.
How and when would you use these features? A bandpass filter, an EQ, maybe even a notch filter.

Hello, It would be nice to have a "pro" feature in the App that allows a poweruser to manipulate more things in the DSP.
A bandpass filter, an EQ, maybe even a notch filter. That would be great.
Been able to manipulate the DSP manually combined with an spectrum analyzer would be great. Doing It by ear could be done but not as precise.
The spectrum analyzer does not need to be incorporated in the app, I could use another app for that and the phone microphone.
That way you could "visually" correct the noise around.
Lets say I have a low frequency noise you want to reduce, I could use a hi-pass filter.
If a electronic device generates a audible noise in a specific frequency, like an old CRT TV or a power adapter with a bad capacitor, then a notch filter could be used.
Also, voice goes from 300 Hz to about 3400 Hz, a configurable bandpass filter could be adapted to different voices and situations.
Thanks for the detailed reply.
You've given me lots of food for thought. I was out last night with my Hearphones and your post had me thinking and listening for sounds that I would want to remove (hi-pass filter), pinpoint and remove (notch filter), or isolate by frequency (bandpass filter).
These are interesting ideas. Thank you for giving me a reason to ponder them.
I forgot to give an example of a possible use for a parametric equalizer.
- If I'm in a room with many people listening to music, I can personalize mi listening experience to my taste.
BTW, a good visual interface of bandpass, high-pass and notch filters does not need to be complicated to regular users. They do not need to know anything about db, octave, white or pink noise, etc...
Just see things in the screen, swipe and hear the changes.
An equalizer feature would be of great benefit to me and others with mid-frequency hearing loss, sometimes called cookie-bite hearing loss. I have smart digital hearing aids which compensate for that and also provide directional sensing and bluetooth connectivity. However, they are not great in very noisy environments or for listening to music over bluetooth. The Bose Hearphones sound ideal for those situations but I am concerned that I will have to overboost the high frequencies to fill the gap in the mid-frequencies. An equalizer with 7 or more bands would avoid that. Unfortunately I can't try the hearphones because I live in the UK, but I will probably buy some anyway and see how I get on with them.
