I'll see you in heck!


I've got the Rpi400 and I was wanting to set it up for VDI to my office. I've already been approved and I have it set up on my iPad.

This is just for playing around, as I'm in IT and have VPN/Laptop etc.

Does anyone have a suggestion for the best setup? I just installed Fydeos which is a ChromeOS clone (China built, but OSS). And I was just going to use the stock Citrix android app. Not sure how much I trust it to connect to my office.. Anyone have a better setup? Or can speak to Fydeos's security?

Depends on how much you compress it, but yeah, I've heard some absolutely massive differences.

even just listening to spotify with a direct connection rather than bluetooth you can notice a significant improvement.

a decent DAC goes a long way.

I just grabbed WAVs off bandcamp for everything I had already purchased simply because it was the preselected format. if i start getting a lot of albums this way i will probably switch to FLAC.

found a few known-to-me artists on DSD too so I'll try that out.

what a fun little project.

Is the Spotify integration better? Not having my liked songs playlist available is a bit annoying but I can just airplay from my phone to the Volumio instance to get CD quality playback of lossy Spotify.

Another alternative, and the only one I’ve been satisfied with in a multi room setup, is running forked-daapd in conjunction with shairport-sync. I run forked-daapd on my NAS (a Pi4) and shairport-sync on Pi0Ws attached to dumb speakers. Forked-daap can also do local output, before I got the Pi4 it ran on a Pi3A directly attached to some dumb speakers.

It just shows up in Spotify as another device I can stream to if that's what you mean. It also has Airplay connectivity as well if you have some kind of different setup that needs it.

Cheers. Yeah it sounds like it works just like Volumio in that sense (works as a host for your lossless files or airplay target for anything else) so I'll chuck it on another mSD and give it a try.

Airplay/shairport are streaming from device to device full-time, so it can take a serious toll on your battery if you’re playing from a phone.

With SpotifyConnect, your phone is just a remote control and the music is grabbed directly from the internet.

Theoretically, volumio and moode should have similar Spotify performance since they use the same open source player, but in my experience, moode works smoother and updates the app quicker when Spotify breaks the API.

You’re not going to get playlist access on your Pi either way. Spotify seems to barely tolerate LibreSpot.

Well the Spotify plug in for Volumio takes my credentials and shows my playlists but liked songs has a different name and only shows/plays the last 10 additions to the playlist so it's not very useful.

I installed Volumino on an old Pi and it was nice but my biggest concern was how outdated the OS was. I just installed RaspberryPi OS and mopidy. Works great for subsonic/airsonic. It has support for Spotify but I haven't tried it yet. It does have a web interface and only took a few minutes to get going.

I was literally looking for ways to connect an RPI to Spotify when I saw this, somehow it didn't come up in any of my searches. Getting it connected to Spotify was super simple; it doesn't support spotify connect but it should be controllable from the web interface anyways so meh.

Really depends on the lossy format. For example, the one YouTube uses really fucks with lows.

Youtube uses AAC and Opus, both of which have very good low-frequency characteristics (better than MP3).


Stop getting info from audiophiles who show you an audio sample and say "listen to how bad that is, that's because of compression!" If they tell you which one is compressed, it's not a blind experiment. It's the inverse of the placebo effect. To get a scientific result, you have to listen to the sound without knowing which one is the compressed audio and which is lossless.

I'm not an audiophile, I use cheap pack in cables on almost all my poo poo. But you don't have to be one to notice a difference between Spotify over Bluetooth and Spotify over cables.

The reason I decided to try a rPi setup was because I put CarPlay in my car, stopped using Bluetooth and immediately noticed an improvement in sound quality. I didn't know at the time wireless CarPlay used Airplay, not Bluetooth to transmit the audio, but then confirmed the same improvement using airplay in my house vs Bluetooth (on the same speakers in the same room)

Initially I just wanted the rpi as a Spotify steam box that I could control via Spotify connect - this would get the same functionality of Bluetooth but better sound quality since Spotify connect is just remotely playing/controlling.

Then I stumbled across hat DACs. I'd never really used high end audio playback devices before (I have nice speakers already) so figured I'd dip my toes and here I am.

My ears are kinda hosed after years of playing in bands so that I noticed anything at all, especially in my car of all places was kind of why I went "well if Bluetooth sucks that much, let's see what a WAV file played in a quality DAC with no wireless connectivity sounds like."

The answer? It's diminishing returns but it sounds a lot better than it did.

Would I spend as much money again from scratch? Probably not.

Did I enjoy researching and tinkering with an rPi and intently listening to my favourite albums? Yes.

Tldr it was just a fun project plz don't link me to $500 volume knobs.

I'mma break into your house and replace all your WAVs with copies that I've compressed to MP3 and then re-inflated to WAV, then see how long it takes for you to notice the supposed "low end cut out".

Bluetooth specifically can have terrible quality if it's using SBC encoding, that poo poo is incredibly bad. (It was designed so that a 90-cent chip in late-90s tech could en/decode it in realtime.)

You can tell because he's ignoring how optimizing audio for different purposes works, and it's the probable culprit here.

The tl;dr (because I can only handle anyone talking about this for so long before I get a real bad craving for a drink) is as follows:

Youtube's so ridiculously massive they save a considerable amount of money every little bit of data they save, and the vast majority of content uploaded is recorded using mediocre-at-best equipment. They want the voices of people to come through clearly, so that's where the bulk of their bandwidth allocation goes. Are those lows a musical instrument 90% of viewers can't hear anyway on their lovely phones, road noise, wind, or just someone farting on the mic? Who cares, it's not a priority. Then they make everyone use that solution, because gently caress maintaining multiple answers. They do tweak things every so often, so videos from a certain era might just sound shittier and on average nobody notices.

For your own use, who the gently caress cares about space anymore, use lossless you're not using a 128mb MuVo. Lossy codecs have come a long way but it barely matters. If someone's encoding lossy quality is an afterthought and it's even odds if they're using the right codec for it, or just something built for speech purposes because those things are the cheap answer.

If you want to be able to hear audio from anything else, you have to mix it in which means re-encoding. Anyone here who's set up bitstreaming for surround audio formats on a HTPC has probably dealt with that one before. That's probably fine for streaming music to a speaker around the house, but I'd bet most people would rather their navigation voice comes through along with their music in the car, or that notification tones come through in their headphones.

Bitstreaming MP3 is also possible, but no one does it for the same reason.

One thing I wish someone would do though is just support uncompressed PCM. Bluetooth A2DP technically supports arbitrary codecs so it'd just take a source and sink device agreeing to do it, and there's enough bandwidth to handle the same "CD quality" signal you'd find on a S/PDIF connection with room to spare. No meaningful codec latency, no processing, just take the output from the mixer and wrap it up in some Bluetooth. It'd be great for basically any situation where both source and sink are connected to a significant external power source like a car or the mains.

Completely wrong in every single way. Bullshit you've invented in your head.

You can download youtube vids and look at the encoders they use, you know that right?

Youtube currently uses Opus at 3 different bitrates, and AAC-LC at ~128kbps. They use the open-source encoders for each of these. ffmpeg LAVF for AAC (which is meh compared to apple's or fraunhoffer). And the standard open-source encoder for Opus, because opus is an open-source codec, the successor to Vorbis.

Youtube does not have a special encoder for farting into microphones. They prefer to send you ~128kbps Opus, which is acoustically transparent for music with the vast majority of people & samples, and only send you lower bitrate or AAC if your connection sucks or your device can't decode Opus.

Im not sure why Youtube came up as I wasnt using it, but interesting all the same.

music is definitely auditioned on all kinds of amazing/lovely speaker setups but for the most part it is still produced at the absolute highest quality they can get for the masters and then if theres glaring issues with the mp3/spotify/whatever compression they might go back and have a look at it again.

my own experience of being in a band and recording a CD and putting it on itunes was that itunes wants the WAVs and they do their own compression. I would imagine spotify is the same and bandcamp is definitely the same since you can choose to download flac or WAV when purchased.
