November 13. 2012

Today I contacted GenAudio via e-mail and asked whether AstoundSound for Mountain Lion will be released in 2012 as stated on their website or if development been halted?

Within a couple of hours I received this response:

"GenAudio is focusing on other business efforts and has yet to determine if the AstoundSound Expander will be revived or discontinued. We will continue to evaluate this decision."

Based on the amount of time that has passed since the software was upgraded for Snow Leopard and the above reply, I wouldn't make any bets that AstoundSound Expander is going to be "revived."

That is a shame because I think that it significantly improves the sound quality when using small external computer speakers.

Works really well.

Needs update to Lion-the developer says they're "working on it" and it does work in Lion, though the control panel needs to relaunch in 32-bit, and crashes after you make adjustments to it. Sounds like a simple fix, though it's not done yet.
So, back to the software-it enhances all audio through the computer, so music sounds richer, and it adds additional "space" to music. Sounds like you're playing your tunes on high-end equipment.
I've tried all of the available audio enhancers through the years, and this one works quite well, though desperately needs an update.

I use this in conjunction with Hear, Digital Power Station, and iWow. The effect is close to breath-taking whether I'm listening through Bose Computer MusicMonitors or through Sony MDR7509 headphones.

I have no pretense of being an audiophile, but I know what I like and it works for me.

My only worry is that GenAudio is not bothering to update this. A relaunch of Sys Prefs is necessary to get it to work. IME, this is the beginning of the end. Take a look at Volume Logic's fate after it was bought, for no obvious reason, by Plantronics.

GenAudio says that they are n the process of preparing a free-to-registered-owners, compatible-with-10.6+ update to AstoundSound Expander that will drop real soon, now.
Good news, if true. Let's hope.

I just went from an iMac to a new MacBook Pro. This worked, and sounded very nice on the iMac. I can't seem to get it to run on the MBP.

Sent a support request 2 days ago but haven't heard back yet.

I sure hope there is an update soon, especially 64-bit. I sure miss the sound.

I sent a copy of my first post (above) to them and they answered right away. Maybe you have to accuse them of letting AstoundSound Expander become abandonware and they should release to SourceForge or someplace, instead, to make them answer you!;-)

The current version is 3.0.3. The GUI shown is either a fake or the Windoze version. The Mac GUI is as bad as it's always been.
If a prefpane has to be restarted, in order to make a change in the prefs take, then the PP is not really SL- compatible. Let's hope that their beavering away at making ASE compatible with Lion is what has kept them from doing little more than ensuring that ASE doesn't crash and then calling that "compatibility."

The requirements here at Macupdate state Intel and 10.6, but that's not the case. According to their website they support 10.5.1 or greater.
Having said that, I could not get it to run on my system under 10.5.8. It would start, work for a fraction of a second and then silence. This seems to be common, since they have the following under support:
"I was playing audio through AstoundSound Expander and now I hear no audio."
Unfortunately their workaround did not work for me. I really wanted to try it since Bongiovi DPS only works in iTunes and HEAR is just awful.

Snow Leopard and 32-bit are completely independent topics. Snow Leopard is a 64-bit operating system that uses a 32-bit kernel out of the box. This allows 32-bit applications (of which most OS X apps are) to run without issue, until such a time that the developers of those applications rewrites them to be fully 64-bit compatible. There is a special mode of Snow Leopard that allows a user to configure the operating system to run as a full 64-bit kernel. However, 32-bit will not run in this mode, which is why Apple does not ship Snow Leopard with this mode enabled by default. The AstoundSound Expander is Snow Leopard compatible (as a 32-bit application for now) from the perspective of the virtual audio device it uses to capture all audio for processing. Apple changed some of the audio infrastructure at the kernel level between Leopard and Snow Leopard. This is what we mean when we say that we are Snow Leopard compatible.

Regarding processing and Snow Leopard Compatibility:
These are two completely different and unrelated issues. There was in fact a significant increase in both memory and processor efficiency in version 3.x of ASE. Version 2.x typically saw 18% or higher CPU usage. Part of the ~5% usage we see today is the virtual audio device that captures all audio on the system and routes it to the ASE process. The other is the ASE process itself, which uses very complex and sophisticated, Pro-audio level, proprietary, 3D localization digital signal processing routines to create the stereo expansion effect.

In regards to music:
The 3 listening modes in ASE are generalized for those categories of audio. There is no intent to provide highly specific settings for all the various types of music available. That would simply not be possible. However, knowing that Movie mode provides a more prominent center channel, this may be more appropriate for listening to a-cappella or solo acoustic guitar. The nine different settings (3 expansion settings for each of the 3 listening modes) of ASE are intended to provide a spectrum of stereo expansiveness. Though we provide some guidance to the listener, via our naming convention, we understand that listening tastes are unique to each individual. Our settings were created so that at least one of the settings should appeal to most listeners.


The AstoundSound Expander (as stated in the User Guide and on our web site) uses special 3-d spatialization/localization DSP algorithms to expand the stereo image of all audio on the system, while not compromising center channel information or low frequency effect. The User Guide says it this way, "The AstoundSound Expander is always running in the background processing audio from all applications. It takes any stereo audio as input and produces a significantly wider stereo image, while preserving center information (e.g. vocals or center staged instruments), in real time. The result is a wider, fuller and richer listening experience."

The ASE processes 2-channel stereo information. If your system is using a subwoofer, the cross-over circuitry in the sub will appropriately route the LFE to the sub and all higher frequencies to the main speakers. The ASE process is independent of this, as it only supplies the localized (stereo expanded) audio signal to the output device (internal speakers, line-out, headphone-out, etc).

@Espirion

Can you submit a ticket through our support page so that we can help you get this working properly? We are 10.6 compatible and our testing on previous version have passed 100%.

Regards,

Kelly

Thanks for the thorough explanation Kelly, but as I mentioned I'm using 10.5.8, not 10.6 :-)

I was interested in the software given today's sale, but the sale ends in 4 hours so I'll pass this time.

If you find it useful I can record a small video showing the problem and will send it to you along with any relevant information. I was consistently able to reproduce the issue. Just let me know. I'll check back Macupdate when I return tonight.

I'm very confused about this release. They said it's 10.6 compatible; however I remarked about it being a 32 bit application in their last release. This is STILL a 32 bit application.

With the system idle, it is using 5.20% of my CPU.

Regarding CPU time, on the boot after installing it, I see it's second highest user of the launchd processes:
CleanApp Daemon is #1, followed by AstoundStereo, followed by WindowServer and everything else I run on my MacBook Pro.

It would appear that process efficiency is unrelated to Snow Leopard compatibility.

It works. The sound gets louder as I increase the 'power' on the pre-amp. It's unclear as to how the sound is modified between the 3 choices: movies, music and games.

But let's stay with music: I would expect acoustic guitar to have a different profile from an electric bass. I'd expect a piano to have a different configuration from an a-capella group.

If such exists, it's hidden. This is hard stuff to get right and there's a trade-off between being easy to use and trying to accurately reproduce the sound, given your hardware (how does it know if I have a sub-woofer and if it is handling the lows properly without booming? The documentation doesn't say, nor does it refer to such.

I'm unsure what this product does. That's not a good place to be.

Still 32-bit. According to their website, they believe that's what Snow Leopard users are running (the 32-bit kernel).

I'm very disappointed with this product that was promising when first introduced.

What? There still isn't a SL 10.6.3 compatible update? Do the ASE people even care about their customers? Is there a way to get my money back?

well. it's been nearly 8 months of waiting for a SL compatible version. and now that 10.6.3 came out I have to assume I will have hearing loss by the time a working version comes out.

I sure am glad I paid for this.

I have tried almost all software solutions for audio enhancement on different models of iMac (SRS iWow, AstoundStereo Expander, Joesoft Hear and even latest Bongiovi Acoustics DPS). Most of these software solutions make music artificial and unnecessary louder and most of the time they do not match up properly with your audio hardware (I am using external DAC, amplifier and speakers).

Worst still many of these software solutions are not compatible with latest versions of Mac OS X (10.6.3 running in 64-bit mode) and developers have no will to provide prompt support (how many months have passed ?). So I give up on software plugin and go for hardware enhancer such as units built by BBE or Behringer.

So unless you don't want to spend too much on audio enhancement for basic audio setup (not using external DAC/amplifier), these software solutions are not for you.

Sadly, the developers of ASE seem to have given up on fixing their problems with SL 10.6.x! I am an ASE "registered user" and I am totally dissatisfied with this product! If your are interested in a sound expander for iTunes 9.x, try SRS iWOW; it works correctly with all versions of SL! My previous review of ASE is reduced to zero stars! Be careful, if you are considering; I won't!

I have installed the updated version of ASE and it works as advertised with SL 10.6.3. It took awhile, but ASE again looks good.
