Would RuneAudio support I2S output on Odroid C1+ ?

Pulseaudio equalizer

Having just had an audio test I've had my suspicions confirmed that I'm experiencing the "canonical" decline in my hearing for my age-group (80 +), exhibiting a distinct falling-off in the 2 to 5 KHz part of the spectrum (and progressively more at higher frequencies). Up to 5KHz I'm still hearing "normally" (ie up to 60 dB) and above that I hear at least something! However from 2 KHz upwards attenuation - very mild at first - begins to set in.

I mentioned the 2 - 5 KHz range (above) because that's where speech starts being affected I was told - consonants begin to get progressively less audible (vowels are still unaffected) and that causes speech to start to become more blurry - which is exactly what I had begun to notice, albeit a fairly subtle effect, and which prompted me to have the hearing-test.

So, this doesn't mean I need a hearing-aid. But it does mean that I could benefit considerably from having an equalizer in the signal-path. Hence this post.

I've been looking into how I might be able to achieve that. A hardware component is out of the question (too expensive, bulky, overkill...) but it seems to me that Pulseaudio might give me just what I need. Here's the outcome of my attempt to explore that possibility - using the command-line for an ArchLinux install

Hi Frank

Thanks for the reply.

I'll work on that.
