It seems, that due to being a competitive shootist in my earlier years, coupled with years of motor-cycling before the industry invented low wind-noise helmets, under domestic pressure I will now have to wear hearing aids. A recent hearing test shows that my hearing is OK at low frequencies, but tails off rapidly as the frequency increases.
I often listen to music in the evenings using my Stax or Sennheiser headphones, while MrsLadyWife watches TV, but I now need to shape the sound to match my hearing, as per the hearing aid graphs. I have a good graphic equalizer loaded on my Android, and some good headphones to go with it, so I need to be able to plug a Bluetooth or WiFi thingy into the RCA out from my pre-amp, and pick it up on my Android, and thus to the headphones.
So - does the hive mind of CP have any suggestions of how I should set about this? What kind of 'thingy' do I need? I should point out that headphones cannot be used with the hearing aids I am currently evaluating, and anyway, the sound quality is very poor.
Please shout your reply very loudly, or I won't hear you.

PARDON!
Please send me you Stax headphones (I already have the Sennheiser HD-650) It would appear you are not making best use of them.

You may be onto something there Griff, personally I would get the new ChromeCast Audio device.
Then using the eq function in something like BubbleUpnp you could adjust the eq as required.
I'm not sure if it would work, yet, I'm picking up my ChromeCast Audio device tonight, I will update when I've tried it.

second the vote for chromecast audio. It's only about $10 more expensive than the cheapest chinese junk-quality wifi dlna box, and works reliably.
|
|
|
|

Yes, I just got mine today, setup was simple and the audio quality seems good.
I'm streaming FLAC to it from my media server and its working fine, not sure if its loss-less or converted on the fly, I'm guessing loss-less.
|

Thanks for that - I found it earlier, but I think it works the wrong way. I want a magic thingy that sucks music out of the pre-amp, digitizes it, and sends it to the Android, whereas that seems to take the Wi-Fi signal and push it to the HiFi RCA connector.
|
|
|
|
|
Would SoundWire work for you? I'm not sure as I've never tried it, it uses a PC(with line-in) to digitise and send the audio, you should be able to equalise at the PC. Is your source mainly analogue?
|
|
|
|
|
Honestly, this might be something that would be a good Raspberry PI project, since you'll also need to run an analog-to-digital conversion on the signal coming across the RCA. I'd be surprised if you could find a COTS product that will do what you want it to out of the box, at least not at a reasonable price.
I'm afraid that I don't know enough about analog-to-digital processing to make a good recommendation on approach, though.

Sorry - I don't indulge in the black arts, for fear of damning my eternal soul!
I do LOB/DB stuff.

Same boat, but never afraid of playing with things that have wires!
Soul was sold off for an excellent cheeseburger some years ago, though.

Equalizer --> Bluetooth Adapter --> Phone --> headphones --> your ears, seems like a lot of steps. More steps equal more areas for sound degradation?
Bluetooth is getting better, but it still leaves me wanting more, sometimes.
|
|
|
|
|
I agree about the degradation, but my ears are already pretty degraded.
|
|

I don't think its possible to send audio via Bluetooth to a phone, Bluetooth has strict source/sink rules. Omit the phone and use Bluetooth headphones (which are getting much better, but not Stax better) and what you suggest would work.
|
|
|
|
|
Why not? I use hands-free via bluetooth in the car and, unless I'm missing something, that is sending audio to the phone.

Isn't it a bit too early to be "On the Gin" Nagy?
Unless I'm missing something, aren't you sending audio from the phone via Bluetooth when doing hands-free.
Unless you mean the voice command to do the dialling, in that case I'm not sure how that works, it must be Voodoo magic.
|
|

No, you are missing something.
I speak, this causes microphones fitted to the car to vibrate and create an electrical signal.
The signal is transmitted to the phone via bluetooth and that sends it out through the cellular network. The callers inbound messages go from the phone via bluetooth to the car's audio system and out to the speakers.

Oops  yes of course you are correct...
I take back what I said about the gin.
All I can offer in my defence is that for HQ audio transfer we are usually taking about AVDTP, the voice link is a different part of the Bluetooth protocol and much lower quality.
