Converting stereo sound to surround

I've recently purchased an external USB 7.1 sound card. I needed this to separate the front and center/bass outputs. My problem is whenever I use an application that only supports stereo sound (spotify, etc), I'm only getting sound out of the front speakers and nothing out of the center/bass. If I play a sound clip that is 7.1 or 5.1 I do get audio out of all channels. I've looked online to no avail; All of the guides I found where outdated and didn't help. I'm just wondering if there are any up-to-date solutions to this?
I'm running 10.9.5
Thank you!

Upconverting Stereo sound to Surround 5.1 or higher?

Does something of the sort exist for linux? I'm just having a hard time living without the "CMSS-3D" feature of the windows soundblaster drivers. They also have an alternative called DTS:Connect which includes DTS:Neo PC (which i could use) and DTS:Interactive, is there any way to utilize those functions of my card?
Creative's Crystalizer and Sound Volume Management i can live without in fact i can live without everything except equalizer and Stereo to Surround conversion, it's the latter i'm having a hard time finding on linux, do you know any solution to this problem?

That's one useful sig you've got there , Thanks!
Right now i'm just focusing on converting stereo sound into 5.1, i'll need to play a bit with the config file (since i have very rarely configured it) to test that function though so i don't know yet if i need any additional effects or distortion, but it would be nice to know about which ones are available, i quite like tweaking my sound to perfection, thats why i even have a soundblaster card to begin with.
Quoting Wikipedia on an effect that i do like to use (Crystalizer, but as i said before i don't think it's something really important to me)
Creative Labs states that the primary function of the Crystalizer is to "restore portions of the sound which were lost during compression". The "compression" that is meant here is not the digital file-size reduction achieved by digital audio data compression technologies like for example mp3. Rather, the idea is to reverse the effects of dynamic range compression, an analog technique that was and is used during the production of most 1990s and newer Audio CDs (with the exception of some classical music recordings) to make them sound louder at the same volume level setting, as it was found that subjectively louder CDs get more airplay and sell better. To achieve this loudness without introducing strong distortion, points in the signal where the volume reaches a maximum are compressed (which means in this case: reduced in volume), then the whole signal is multiplied by a factor so that the maximum volume is reached again. After this, the music as a whole is louder than it was before, but the maximum volume points (mostly transients) are not as pronounced as they were before. Since this whole process is done before the final Audio CD is recorded, its effect is equally present in uncompressed audio files created from such a CD, in lossless compressed audio made from the CD, as well as in lossy compressed audio from that same CD. Transients are typically found in percussive sounds, in plosive consonants of voice recordings, and during the first few milliseconds (the so called attack phase) of non-percussive instrument sounds. All these tend to be somewhat muffled by dynamic range compression.
To undo this effect, the Crystalizer uses a multiband compander (compressor/expander) with dynamically adjusted compression/expansion. Its main function is to detect transients and to increase their relative volume level. As a consequence of enabling the Crystalizer, the signal is altered, and whether the result improves upon the input audio is purely a matter of perception and can depend on the type of audio being played.

Stereo sound into 7.1

Hey guys,
Anyone know a tutorial i can follow or some setps on making windows media player play stereo sound (two channels) into 7.1 sound? I have been told that some players have a setting to convert stereo sound into 7.1 surround sound. Any help is appreciated.

How do I convert analogue 5.1 surround sound into a digital signal? (Pioneer SE-DIR800C headphon

I understand that my SB Audigy 2 card will only output 5. sound from games through its 3 analogue connectors. How do I convert this analogue signal into a digital one? What hardware do I need to purchase?
I have read the thread on "Digital Connections, SPDIF and Dolby Digital Info", and also I've thoroughly read the "Creative Speaker Connectivity Guide".
The reason I ask is that I have just bought a pair of Pioneer SE-DIR800C Surround Sound headphones. This are supposedly fantastic for recreating surround sound on headphones because there is a clever little decoder box. They accept a DTS / Dolby Digital signal via the digital co-axial and optical inputs, and there is a single analogue input which only accepts stereo sound.
My XBox and PS2 will output true digital 5. sound via an optical cable and I am confident this will work perfectly with these headphones. I'm really looking forward to playing Halo in surround sound! But for gaming on my PC, I'll be limited to just an analogue stereo signal. Well, unless I can find some device that will convert my SoundBlaster's analogue 5. outputs into a digital signal, which I can then plug into the little decoder box for these headphones.
So, back to my question:
What hardware do I need to buy to convert an analogue 5. signal (via 6 x RCA or 3 x 3.5mm stereo ) into a true digital signal (via optical or co-axial SP/DIF)? Is it some type of headphone amplifier I need? If possible, please recommend makes & models of equipment.

Thanks stefan
OK, basically I have found 3 options for getting digital 5. out of a PC:
a) Creative DTS-60 (approx $90). This converts the SB's analogue into digital, but it's not available in the UK and it also introduces a noticeable 50ms sound delay. Also, who wants an extra box hanging out of their PC?
b) Buy a new sound card which has Dolby Digital Li've output. For example, ) BlueGears HDA X Mystique 7., or 2) Turtle Beach Montego DDL, or 3) Terratec Aureon 7. PCI (NOT the Space, FireWire or Uni'verse cards). I couldn't find the first two available in the UK so I have just ordered the Terratec card from Komplett.
c) Buy a new motherboard that has built-in Dolby Digital Li've output, for example the ABIT Fatalty AA8XE. Unfortunately my PC is only just over year old and I'm not quite ready to replace it.
I hope this info is useful for people. Maybe Creative will start making a card with DDL output too.Message Edited by NinjaHeretic on 2-22-2005 08:46 AM

Can't get Surround Sound from a stereo sound file

I have tried multiple times to get the surround panner to work on any of the stereo clips that are included with STP2, but it stays in stereo. If I put the surround panner all the way to anything but the left or right channel I get NO sound. Surround sound is working fine for clips that are 5.1.
Anyone have any clues as to why this is not working?
If I pick a audio clip that is surround, the panning works and sounds fine. But looking at the demo movie on Apples website, it should be no problem to put a stereo file into any of the surround speakers.
I got a new HD coming and I am going to install everything fresh.. OS and all and see if that fixes things.

I'm not sure if this helps because I new to this having only picked up Soundtrack Pro for the first time a couple of weeks ago, but I was having the same problem until I moved the widner on the Surround sound HUD to full (fully to the right). Suddenly my stereo went into all 5 channels! (I'm trying to make 5.1 from stereo at the moment) Now I could move the puck and the sound would go to that speaker. But yeah... it's something i don't see in the manual and had to figure out for myself. Only took two weeks...

No stereo sound from I/O

Hey all! I have an Audigy 2 ZS Platinum Pro card, and for some reason I cannot get any stereo sound (only mono) from the I/O hub, both through the headphone out, as well as through the headphone out on a MIDI controller plugged into the hub via firewire.
5. Surround Sound works in all 5 speakers connected through the analog miniplugs on the card, and stereo sound works through the headphones when they are plugged directly into the speakers via a headphone out there.
Any suggestions as to how to get stereo sound to work from the I/O hub?Message Edited by freechus9 on 07-30-200707:00 PM

anyone?

Does Dinal Cut Pro X support stereo sound?

Does final cut pro support stereo sound?

I am going to answer my own question. It looks like not only stereo but 5.1 surround sound.
I looked up the specs.

Stereo sound from all speake

Hii, I have a X-Fi Xtreme music and a 5. speaker setup, can someone tell me how can I get stereo sound from all of my speakers? thanks in advance.

Hmmm, I don't have an X-Fi, but to answer your question the first thing someone needs to know is how you have your speakers connected. If, for example, you're running throgh a receiver you need to separately output each channel (using 3.5mm mini plug to RCA cables/converters you would buy at Radio Shack) to the external decoder of your receiver. Of course, in that insance, you would output the DD source stream from the optical out of the card through the optical in of the receiver; stereo playback would be from a 2. signal. I run both configs on mine. Now, if you're running computer speakers already plugged into the correct outputs of the sound card that's a different question, and it's one I can only relate from my experience with the Audigy 2 software.

Stereo sound using SO Write

Hi.
I'm trying to play one tone out of my left speaker and another on my right.
I have configured my sound devise to stereo using "SO CONFIG". Then I send
the tones to "SO Write" using a 2d array.
I hear to tones, but the problem is that the same sound is coming from both
speakers.
I need to have the tones separate to each speaker.
Any help would be greatly appreciated.

You may want to post this to a Data Acquisition forum, as you would probably be talking with engineers that have more experience with this sort of thing. However, I do have a bit of experience with it. If you are wanting to send out analog signals to the different speakers independently, you will need to have two different channels to write to. Does your sound card supply this capability? I assume that if a card allows stereo sound, it would have multiple channels to write to. Let us know what you find out.

Ipod doesn't produce stereo sound from iphone built-in speakers?

I've had my iphone for some time now, but just noticed that when playing music from the ipod built-in to the iphone, the music is only coming from one speaker (the one on the bottom left).
Is that normal? I would assume both speakers would be used?
I checked the settings and couldn't find a setting for "stereo sound" and did a forum search and couldn't find an answer.

fair enough i didn't think i had posted it in the right forum, so i posted it in the ipod/audio one as well....
anyway, thanks for the answer.

Are you not getting stereo? What are you listening with - maybe there's a plug problem...

CONVERTING .WMA SOUND FILES TO MP3s ON A MAC

CONVERTING .WMA SOUND FILES TO
MP3s ON A MAC - Written 9/28/07
Here's some help on how to convert .WMA sound
files to MP3 sound files on a Mac. Hope it helps.
1. Open the .WMA sound file in Quicktime.
2. In the Quicktime menu tool bar, go to FILE and
select SAVE AS.
3. Save the .WMA sound file as a self-contained
movie .MOV file. Then create a folder on your desktop
to store the .MOV files that you created.
4. Open iTunes and create a new playlist by
going into FILE in the iTunes menu toolbar and
select NEW PLAYLIST. Then name your playlist.
5. From the folder created on the desktop,
drag the .MOV files into the specific playlist you
created in iTunes.
6. In the specific playlist you created in iTunes,
highlight the .MOV files with your mouse. Then go
to the iTunes menu toolbar and select ADVANCED.
7. In ADVANCED, select CONVERT SELECTION TO MP3**.
Then wait for the iTunes' "ding noise" to let you know the files
have been all converted.
**To have CONVERT SELECTION TO MP3
listed in ADVANCED:
(a) To have CONVERT SELECTION TO MP3 listed in
ADVANCED, go into iTUNES in the iTunes menu
toolbar and select PREFERENCES.
(b) In PREFERENCES, select the ADVANCED icon. In
the ADVANCED icon menu, click on IMPORTING.
(c) In the IMPORTING menu, go to the IMPORT USING line.
Now scroll down and select MP3 ENCODER. The click
on the OK button.
8. After the .MOV files have been converted to MP3 sound files,
erase the .MOV files listed in the specific playlist you created.
9. Take your mouse and click on the MUSIC icon in the LIBRARY section.
Now in the LIBRARY section, search for the converted files.
Once the converted files are found, be sure to highlight one at
a time-- you'll be making sure which ones are mp3s and which are not.
10. Once a converted file is highlighted, go into FILE in the iTunes
menu toolbar. Click on GET INFO and check which files are
.MOV or MP3 files. Delete each .MOV file found.
11. Now you're left with the converted MP3 files in the LIBRARY.
Highlight and drag all the converted MP3 files from the LIBRARY to your
specific playlist you created. Now you're done! Enjoy your
new MP3s!

There is no solution for playing and coverting DRM-protected WMA files on a Mac. I don't even know of a way to covert DRM-protected WMA files on a PC; you normally have to reimport them from the CDs, or when purchased from a download store burn them to an audio CD (where allowed).

Sound Blaster Surround 5.1 USB on GNU/Li

Hi, I need to buy USB sound card for my laptop. Sound Blaster Surround 5. seems to be a good choice, but I am running only Ubuntu Linux, so I need to know if it will be working. I know, that only M$ Windows are supported, but it's working on Linux or not?
Thanks for all responses.

U need to go and set to 5. speakers in the Audio Console for the 5. speakers to work.
