The thing is, opinions about differences in sound quality are not welcome unless they can be backed up with evidence in accordance with our rules (have you read our rules?).  If you don't have acceptable evidence, then don't make them.

I can't tell much from my side. I get an `std::runtime_error` from my decoder, and I bail out as it is assumedly hosed.

None of that is very clear.   All of this should be possible with a regular audio editor (Audacity, etc.), if the filters are fixed.   I'm guessing this is some kind of audio compression and that the filters are not fixed.

More specifically, optimum results have been achieved by using a filter having a 12 decibel per octave slope from 0 to 15,000 cycles per second.
That doesn't make sense unless it's a variable frequency filter.   i.e.  12dB per octave high-pass at 10kHz means something.   A high-pass or low-pass filter has a single cutoff frequency.   A bandpass filter has a low & high cutoff, but a 0-15KHz "bandpass" filter is a low-pass filter.  If it's variable, what controls the cut-off frequency?

In one specific embodiment, this filter is formed by a pair of tuned amplifier circuits each having a 6 decibel per octave slope within the frequency range of interest.
Again, not enough information.

In this embodiment, the speech waveform is preferably combined with a high frequency noise masking signal of lower amplitude prior to processing.
What frequency, what level, and what's the frequency band of this "high frequency noise"?

Another normalize
Then another for clipper
It's kind of unusual to clip after normalizing.    Well...  Since clipping is distortion it's unusual to intentionally clip at all...    Sometimes you normalize after processing to prevent clipping.

For many, audio is a hobby - not a profession. Hobbies involve emotions so we always will find subjective comments in these forums, like this one, which is a crappy opinion coming from a low IQ man that can't back it p with scientific evidence or A/B tests on audio professional and enthusiast random samples.

General Audio / High pass filter, normalize, clipper addon

Hi is there a high pass filter component that will achieve the following

How does it sound if you use the onboard sound? still the same distortion?

If it onboard sounds ok then have you tried updating the drivers for your chord mojo?

it sounds okay i guess, cant really tell since the max volume desktop+k712 is still low to say for sure. i tried checking mojo's site to check for new drivers, checked windows update/device managers aswell. nothing. 16 and 24/44.1/48 is w/ mojo is not that bad when it comes to vocal. but when it comes to 24/96 i can hear the distortion clearly. did i miss something? components? asio4all settings? foobar settings itself? i maxed the sample/bit on windows which is 32/384 ticked allow exclusive. asio4all=512 samples/32 in/out

Audio Hardware / Re: What Headphone Amp sub £250?

So far I'm finding they work well enough directly with my lap top and smart phone and as I say so far I'm really struggling to find any reason not to just buy an integrated amp with a headphone jack.
If you don't have a problem you don't need a separate headphone amp.  

If you feel like you're hearing different frequency response on different systems (at the same volume), that's a clue that you may have an "impedance issue" and a headphone amp should help.   It seems "typical" for headphones to have an impedance bump in the mid-bass range and that will make a bump in frequency response if the amplifier impedance is too high.   (I didn't find an impedance curve for your headphones on Headphone.com.)

But...   Let's say there is an impedance related mid-bass bump (or something else) and you like they way they sound, you may not like the way they sound with a lower impedance amp.

to just buy an integrated amp
It's usually more economical to buy a receiver.   Receivers & Home theater receivers (AKA AVRs= Audio Video Receivers) are mass-produced, mass-distributed, and sold at competitive prices, whereas integrated amps, preamps, and power amps are specialty items.     And with an AVR you get digital inputs and "digital features".    (You may not get Aux/Tape outputs on an AVR and if you're still playing records, phono inputs are extremely rare...   I don't know if phono inputs are still standard on integrated amps.)



Thanks for the advice! I think I'm a traditionalist in some ways, not so much out of conservatism but when I bought my last system I applied a buy once, buy right approach with the intention of keeping it for the long term so I'm not really up to speed on the equipment side. To be honest, there isn't really anything wrong with my old system but I decided after 20 years it owed me nothing and these days I listen more and more to digital files on my lap top or smart phone so want a digital amplifier (or a CD player with connectivity, yes I do listen to my old CDs sometimes so still want a CD player). I'll look at receivers, I've been looking at amplifiers with digital inputs.

using foobar2k on a desktop for 2weeks, using asio4all(tried wasapi push/event aswell) as my output w/chord mojo and k712. whenever i play a music the details are good but when it comes to vocal, i can hear distortion. not sure if its my settings or its the files(which i doubt since i tried it on my phone its not as bad compared to foobar). if im not mistaken my settings are set to bitperfect playback. i also tried listening using spotify premium on my desktop, its bad too. foobar or windows settings not sure whats causing this or if its the track itself.  suggestions would be nice
