I convert it in decimal so 0x0100ac11 > 0x100ac0f.Bit-Perfect Playback…and why you should careĭavid Snyder: By the time you read this, the new Amazon Music HD streaming service, promising “High Definition” audio to the masses, will have been available in the US and several other markets for a month or two. I checked the last firmware it's 0x100ac11. A basic question I saw that the subversion is actually 0x0100ac0f.

I also, upgrade the firmware of my usb card. I just modified the asoundrc for the bit depth. I must do tests to confirm that it follow the rule 'input = output'.Īpparently it keeps sounds from the browser I tested a flac file it output at the desired sample rate.

I did the change in nf after removing every configuration files in the home directory.Īnd sorry, If my english is not so good, or if I look like speaking like a robot. I already changes the /usr/share/alsa/nf to point the & to my Audiogd and checking the right card number with 'aplay -l'. Because when I start my computer the usb output 'pink noise'. I think that something is wrong with my configuration. once alsa has correct configuration it just keeps working - i don't even need to check alsamixer levels Keeping mpd and alsa levels at 100% (no signal gain or reduction) will be bitperfect The DAC has is far superior to gear I have now, so reduction in bit-depth is likely to be more noticeable. I am over 50 and went to lot of live gigs in my younger days, so my hearing has deteriorated. I have tried this out and could not hear much difference on speakers, but noticeable on headphones. similar effect to downsampling with possible loss of sound quality There is a smaller range of digital values, reduced resolution.

it is based on stuff i learned in analog audio years ago that I adapted to digital looks to have got it, and corrected my mistake - it is half the bit-depth not half the bitsĪt 100% volume, DAC will reproduce full range signal 0-255.Īt 50% volume, DAC will reproduce signal range 0-128. Sorry, I don't have a good source to back this up.

for a 96khz it switch automatically at the equal samplerate ). Like mpd does ! My mpd configuration file can select the appropriate samplerate for a file. I just want to play at the samplerate input. Here's the capabilities of my card : Audio-gd Audio-gd at usb-0000:00:14.0-5, high speed : USB Audio I have heard there are a pre-compiled versions available, but not seen anything i can test in Manjaro yet Have you considered using Firefox in JACK? This isn't available by default in Firefox, but recent versions of firefox-nightly can be compiled for JACK.

This is going to be a growing problem as more packages move to Pulseaudio and versions they need get older and reach EOL They are keeping older versions of Firefox as newer versions are Pulseaudio only. I still have some old-school Linux friends who still refuse pulseaudio (still clinging to FUD about issues that are either wrong or have been sorted out in newer versions of Pulseaudio). If your audio device has an analog volume control you can achieve this - set all digital levels to 100% and only use the final volume control to set a level. if volume is reduced 50% before it reaches the DAC, the analog output will only use half the available bits. I suspect it won't and would be better not using it and keep it simple and more functional, but only way to know for sure is test both and decide for yourself.īest way to get improved audio many seem to miss is making sure alsa levels are kept at 100%, and other volume controls in the digital chain. Suggest you try some testing with and without that asoundrc to determine if it makes any difference. without an asoundrc, sound card should be able to switch to higher bitrate when required. locking it down to only work at 44.1kHz seems counterintuitive. Are you sure you need that asoundrc? locking it to higher sample rate to avoid downsampling makes sense for dedicated use with high quality source material.
