Ubuntu Multimedia :: Bit Streaming / Avoiding Resampling Audio Frequencies
May 29, 2011
I have recently purchase some audio equipment and am wanting to get the most out of it. From what I've read, an OS/media player will tend to "resample" audio frequencies at the software/soundcard level before sending it, and from what I gather, that isn't a perfect 1-to-1 copy of my audio to my speaker. My equipment:
Ubuntu: 11.04 x64
Mobo (integrated sound): ASUS P5QL-CM - S/PDIF out on Intel G45 chipset / VT1708B, 8-Channel High-Definition Audio CODEC
AV receiver: Onkyo HT-R380 (PDF manual)
Speakers: Stereo (connected to 'A' ouput on AVR) - Acoustic Research Red Box II (circa early 90s)
I have the ASUS S/PDIF 'addon' and I have Ubuntu set to send audio through that. I think "bit streaming" is what I am after but I am at a loss as to how to make it happen.

This is 16 bit / 44100 Hz sample. Try to plyback this sample in your favorite music player, and after that try to use command "play SB_test.wav". You see, second part of this file sounds very differently. This is because all your 44100 Hz audio resampled 48000 Hz. It's ok if you watch DVD's (48000 Hz audio), but nasty if you listen CD-Audio (44100 Hz), DVD-Audio or Blu-ray (24 bit / 96000 Hz and 192000 Hz). My question is: how to playback audio with different characteristics without resampling?

I mostly need it to filter away background noise from interviews. So, the editor should allow me to tweak the recordings in the frequency domain. I'm a Kubuntu user, so, if possible, propose me KDE apps!

Use Freecorder in Win7 to record streaming audio and save it as an mp3. Anyone know of a similar program for Ubuntu 10.04? Tried Sound Recorder but I guess that's just for a microphone. Streamripper only seems to work on ShoutCast.

I haven't gotten an answer from Second Life fora so I thought I'd ask here. I'm using Ubuntu (lucid) x86_64. Totem, Rhythmbox etc all work correctly but I fail to get any streaming audio from any of the Second Life clients I've tried. In some cases I can copy the media url into rhythmbox and run the sound from there but in most cases the url is "hidden".

I need my Ubuntu box to play an http audio stream on boot. It must heedlessly attempt to reconnect to the audio stream no matter how many network errors I may or may not have.
Currently using VLC on boot with the commands: -loop -http-reconnect
VLC works fine for the first little while, but after a day or two, it doesn't try to reconnect enough to meet my needs.

I want to record some streaming internet radio talk shows and music performances on NPR, and I'm wondering what my options are in Ubuntu. I'm looking for something that can output high quality lossless files in several formats, hopefully including mp3 and ogg.

Got my system's audio up, but I'm having a real problem keeping streaming audio going, either in VLC or in the default movie player thing.It'll go for a while and then just stop. I guess it's having a problem with "resume" function or buffering.Any thoughts on this? I'm not having that problem with VLC in XP on the same connection.

Have any of the main music streaming sites (ex. Pandora, Rhapsody, Grooveshark, etc.) made it possible to stream audio without using flash, (other than via iPhone apps)? Have any of them made any strides with regard to implementing html5 functionality?
I know html5 will make more options available for streaming audio over the web, but I have not seen or used html5 for anything yet. The only method that I know of for streaming audio without flash, although I haven't tried it, is via html5 video on ...... This is certainly a suboptimal method for streaming music since the audio quality cannot be guaranteed and is likely mediocre. Nonetheless, I've heard that it works. Also, as a second unrelated question, are there any open source flash players that you guys have used to stream audio from these music sites? I tried a group of different players like Gnash about 6 months ago and failed to stream Pandora or Grooveshark.

I have configured PulseAudio with an MPD system-wide as I want to run PulseAudio without an X-Window Server environment, as I'm going to let my netbook act as a "wireless speaker" for espeak to speak out; thus, minimizing the expense of getting a "whole-apartment audio equipment." This is something that I can figure this out, as I have configured PulseAudio to act as a sender by having a separate RTP stream when I configure it in a VNC client.
Plus, I want my Windows Vista 64-Bit machine to receive the output from PulseAudio. I did download the Windows version of PulseAudio from Cendio, but I have problems getting PulseAudio to work, even if I added load-module module-rtp-recv to default.pa in the PulseAudio directory that I installed in PulseAudio directory. I get error after error messages when I run pulseaudio.exe, so it looks to me that it's not going to work anyway.
So I deleted the entire PulseAudio directory. It said something about entropy that I did not know anything about it. So anyway, is there some sort of a server program that listens to PulseAudio output and then send that audio to the client? The server program in the Ubuntu Server (that I plan to use as a sender) must be able to run without an X-Window environment. Is this possible?
I tried to do a search when it comes to streaming audio from Linux to Windows, but the Google search result came up with "Streaming audio/sound from Windows to Linux" which did not turn out very well for me. As a result, I have no luck with doing a Google search for what I'm looking for. In short, is there some kind of daemon that listens for audio and distribute the sound to Windows? It will be for my internal network only.

I've got a small problem with Banshee that I need some help with, if possible. I'm currently using the latest version of Ubuntu 11.04 and it's up to date. The problem i'm having is with Banshee playing music files over my DAAP share. My DAAP server is running Firefly (mt-daapd), and Banshee can see the server and shares just fine. It loads the song list from the server, but when I select a song to play it just sits there. Rhythmbox works just fine, sees the share and plays the songs ok (which is what i've fallen back to for the moment), so I know it's not a hardware or software problem from the sound "system".
Other features of Banshee play just fine, including internet radio stations, internet archives, and importing songs from the server (which makes the song local instead of networked from a single source). Ok, so streaming from the DAAP share isn't working; here's the output from the terninal I started Banshee from:
[-----START-----]
[Info 07:13:23.440] Running Banshee 2.0.0: [Ubuntu 11.04 (linux-gnu, i686) @ 2011-06-28 05:46:57 UTC]

I am fed up of listening to my (Windows XP) gaming computer through headphones so I want to get it hooked to the stereo.
Rather than use a heck of a lot of wire, I can sit my Ubuntu 9.10 netbook on top of the stereo and stream the audio across WiFi.
So, ideally what I am after is something to capture the outgoing audio on the Windows computer, stream it across the wifi to the Ubuntu netbook and finally play it through the speakers.

i have opensuse 11.3 (64-bit) installed. kde version. my sound card is a creative labs sound blaster x-fi xtreme audio, pcie interface. i am able to listen to cd music without any problems but i am unable to get streaming audio when i visit any internet radio site, videos, yahoo!tv, etc. etc. for instance, when i visit videos, the video part is ok but i cannot hear anything through the speakers. something similar happens when for instance i go to [url] and select any of the music channels. a new window pops up but the music never even starts to stream.
i know for a fact that both sound card and speakers work fine because i've tested them with windows xp. so there must be some setting in opensuse that i've missed. the weird part is that i can listen to music cds without any problems...

Excuse my ignorance of the technology behind the programs, but could someone recommend me a program for Ubuntu that will support music streaming, specifically that from windows Media Player 12.When in WMP12 you can select "play to" and it present a drop of supported devices and computers, and ideally I would to see my Unbuntu system in there, and that the machine be able to play the audio without interaction from myself.

I want to use Ubuntu, but I'd like to listen to my favourite audio stream like I do for Windows.I have installed Audacious from the Synaptic Package Manager when I found out that my new Ubuntu installation didn't install an audio device as part of its installation, and then I installed something called 'Xine' as prompted when,after I went to the home-page of my audio source,I discovered that I needed to install some extra 'codecs'.However, I still cannot get the familiar noise that surrounds me when I'm working within Windows to play on Ubuntu. No noise is produced. What's going on?

I've tried every how-to I can find! If it simply not possible to stream audio with pulseaudio?Flumotion says all audio devices are busy, no matter what i do!My perfered method would be icecast with pulse, but I can't get it to work! Icecast is no problem but the streams are always blank! The only suitable method I can find is using gst:
Any suggestion? Even better would be a audio streaming distro as I have a dedicated pc, but I'm having no luck with that also.

I used to be able to do so with Windows, but not on Ubuntu. I tried everything, even the Sound recorder, and that doesn't work, either. The sound recorder barely registers the audio and Audacity just will not work no matter what I try.

Using Iceweasel on Gnome GUI the streaming audio does not work. Just kind of hangs when the Iceweasel player window opens. It used to work on this machine. I am all updated.Also, is there a way to play the streams that like to open their own players on the Movie Player? I have had best luck playing streams on the Movie Player in the past.

I listen to streaming audio a lot. All types of music, news, talk radio, etc.I have found that the Totem movie player is the most reliable player. Rythmbox is good too but seams to drop the streams a little more that Totem. The main problem with Totem is that I find the play list kind of clunky to use.
Q1: Are there better players for streaming audio?
A lot of radio stations now open in there own "players". I don't like all of the advertisements and other bandwidth eating crap in these "players".
Q2: Is there a way to get the URL of the stream from one of these "players" and play it on Totem or Rythmbox?

I have a gigabyte MB/rig connected to Svideo out on my TV. I have external PC speakers connected to my sound card. For some reason when I go to play video, streaming audio, or streaming video I get no sound. I go into alsamixer via CLI and all is unmuted. I reboot, sound is back. The next day I load boxee, no sound. It's not just boxee when I have no sound. If I close boxee and open vlc and stream online radio, I get no sound either. Reboot, sound is back. No external errors of hardware conflicts either.

I was wondering if anyone knew of any [client] software that takes an audio stream from an input - the mic - samples it, optionally codes it with a codec, and then packetize it to send over the network to an IP address and port number.And on the same machine and other machines can be [server] software listening on a port that would take any packets arriving on that port from another IP address, depacketize it, optionally decode it, and output it - to the speaker.
I'm trying to allow voice over a MANET / Mesh network in a cave, with no outside connection, so can't rely on logging in to other nets or server based VoIP.
