Live 7 improved audio engine?

Post by Briangoodman » Sun Dec 02, 2007 10:45 pm

Hi Live users. I have yet to upgrade but have downloaded the demo to check out the new features. I have read many people stating they hear an improved audio engine but in all honesty I don't hear any difference.


I tested the exact same live set with version 6 and version 7 both running on the same computer with the same plug-in's and VST synths. Holding down ctrl tab enables me to switch between the two versions almost instantly.


Can someone explain to me what I should be hearing

:wink:

Yes again as I sit here testing live 6 and 7 before I upgrade (if I upgrade) I would just like to hear a definitive answer from someone who can confirm live 7 audio engine is better than live 6 because as I sit here playing two sets side by side in real time I hear no difference between the two. is this false advertising :?

Reading the Audio Fact Sheet is a good place to start.

I hear a difference, yes. Aside from subjectivity, summing is now 64-bit, as well as several other optimizations. I'm sure the difference varies from project to project. My high track count projects sound cleaner, and seem to have greater depth. The EQ8, Compressor, and Saturator are upgraded and I can definitely hear a significant difference, and they help to make a cleaner mix when using these devices.

yes, compressor and EQ8 are definately sounding a wee bit clearer to my ears, but the most significant improvement is in Operator, that almost sounds like a new super super synth in Live 7 !

if you can't hear a difference, who cares? at least you know it doesn't sound worse. there's a lot more reasons to consider Live 7 over 6.

Thank you for the answers

Ethois4 > Where would I find the audio fact sheet. I dont own Live 7 I am considering upgrade from 6

Leedsquiteman > You state that compressor and eq sounds better. But in the same set with live six and live 7 I have both being used and notice no difference at all. Yes I could agree operator sounds better and because it is a soft synth made by Ableton they may have made improvements incorporating the 64 bit engine for operator to take advantage of. The problem I see with this claim of better audio engine is that it would mean all old sets using live 6 or 5 (maybe) would suddenly sound better. This makes me sceptical because it would look bad for ableton if they were not up to challenge of making a standard audio engine previously and it took them so many years to get there

Tone Deft > It is only one of my queries before I upgrade but I am a little tired of being charmed by software company claims. But it does matter a lot especially in warping audio but I see no claims of better warping because of 64 but audio engine. But you are right I don't hear any difference at all and I think I can prove there is no difference but will wait to see what other say.

I have read what 64 bit processing can do and spoken with two programmers who told me straight the difference to audio is nothing. The difference is in how audio and vsts are processed and the benefit is more for the software companies that the end user. I cant recall exactly what I was told but at the time it made sense there was no improvement for the sound of the audio. Is this not a matter of headroom and since about five years ago all the software companies had engines with near unlimited headroom (in theory)

Its just that before I upgrade I don't want to be taken for a ride by promotional campaigns and heresy

unfortunately for you one of the reasons that Ableton upgraded the audio engine is because of promotional campaigns and heresy.

in any case it definitely sounds better.

what is 64-bit summing? how does that compare to logic and cubase?

bensuthers > I do not understand what you mean in general with your statement. You say "in any case it definitely sounds better" can you prove this in some way. I am not out to catch anyone it just concerns me that so many say it sounds better but I hear no difference at all. Maybe I am doing something wrong but I have to consider what 64 bit processing means and it doesn't necessarily mean a better sound. If ableton said they have given the audio engine more headroom then I would say mixing would be better or more comfortable but it still wouldn't necessarily mean a better sound. Am I wrong in my reasoning :?

middle of the page here, read the 'Fact Sheets'
http://www.ableton.com/live-7-whats-new
the audio fact sheet will guide you through ways to use Live to make it sound better and avoid things that negatively affect the sound.

btw what monitors do you use?

if you're looking for someone to say it sounds better and give you a measurement, you're not going to get it, it hasn't been done <yet>.

there's more to audio than headroom.

btw umm your software friends are dumbshits if they told you 64 bit won't sound better than 32 bit, things like dynamic range, more accurate math and headroom are obvious answers. I say that because as a generic question: "would a 64 bit DAW sound better than a 32 bit DAW?" the answer is obvious.

Tone Deft > I think its a little rude of you to say the programmers I spoke to are dumbsh**s. I dont mean they are my friends but I was able to speak to them and that is exactly what they told me. I think it would be inappropriate for me to say which company they work for, but you are entitled to your opinion. :wink:

Thank you for the link
Ableton say > "Live 7's enhanced audio engine improves fidelity with precision 64-bit summing at all mix points throughout the program, POW-r dithering, optimized sample-rate conversion and other advances"

I think what they say is vague don't you. Why not say the audio sound is better rather than fidelity and enhanced. I can enhance something with eq or effects. Fidelity could mean many things i think and perhaps the improvement is in the new powr dithering at all mix stages but does this make for a better audio engine. If it does it must be so miniscule and insignificant that it really isn't worth mentioning because through my Dynaudio BM6A's ( that I don't like) I cant hear any difference at all. They are not the most phase accurate monitors in the world but they are not the worst. I prefer my JBL control 1's but the BM6A's reveal much more. I must consider my ears may not be as sharp as they were when I was twenty but I can still mix decently and know when something is different worth mentioning. Its just that I see people here stating awesome sound - its obvious and so on. Im sceptical, very.

They further say
Device High-Quality ModesOperator, Dynamic Tube and Saturator now feature optional High-Quality modes for anti-aliased processing, reducing typical "digital" artifacts.

Yes of course adding a high quality mode to reduce aliasing will have a positive effect but these are for plug-ins and they are not automatically switched on in their natural state so therefor its a processing matter that improves the sound of plug-ins due to programming, its is not because of a better audio engine. Those that claim they hear a difference I predict imagination (except with hi quality mode plug-ins that reduce aliasing) or simply the need to think its better.

yes I agree there is a lot more to audio than headroom but when the software reached decent levels of headroom around five years ago that really was a change we could all hear when mixing. Today it seems software companies simply have to add more features or so called features to keep selling.

You say "if you're looking for someone to say it sounds better and give you a measurement, you're not going to get it, it hasn't been done"

With ableton live perhaps and therefor I cannot take the claims seriously at all. But this is not the case with other software. perhaps you may wish to purchase the mix buss c.d. that was made by a number of professionals a few years ago at a time when the mix buss wasn't quite what it seemed. In fact the c.d. seemed to prove that Digidesigns 888/24 interface was flawed causing a dip in frequency at around 30hz (not their mix engine) and actually showed a couple of other software Daws mix buss were flawed. Digidesign and SSL were involved as well as some highly respected audio engineers so it was very proffesionally done. Things have moved on now and since then there has been little talk of flawed mix engines except live for some reason. Is this perhaps just a reflection of the experience of the users in general. But when I see claims of better audio engine and fidelity I have to wonder what was wrong before then. Were ableton programmers previously not quite up to designing a standard mix buss, after all there is a certain generic form of coding a mix buss. Perhaps no ableton programmers have experience in the real world so to speak. A number of engineers are beginning to question the validity of putting all their trust in 25 year old programmers who have never used a real console - operated in a studio - recorded a band - mixed a record and so on and certainly wouldn't know what a real channel strip is. This is not meant as a derogatory statement but I think we can all agree that marketing and sales is what drives software companies.

Thats enough for me on this subject. I never thought there was anything wrong with Lives engine in the first place. I have my answer, its been within me all the time, my ears and I don't give much heed to 64 bit marketing claims. :wink:

64 bit processing

The problem with answering a complex question with a simple answer. It makes sense that when we're going to end up with an audio CD in a format of 44.1Khz/16bit then having that file originally at 96khz/64 bit doesn't help us at all, it is extra information that we are going to discard before anyone hears it.

But if you are going to modify that file (which is a digital approximation of an infinitely detailed analog wave) in any way using mathematical equations and algorithms (which is what you are doing when you use a program like live to combine waveforms or apply an effect or stretch/warp ) you will get a more accurate result if you start off with a more detailed representation and the process of change does less averaging (or dithering, which I like saying because it makes me think of a tiny little grey haired scientist in a white lab coat agonising over whether 1/3 is .33, .333333333333' or .32), and it will happen quicker if the hardware is built to process bigger chunks (modern processors like 64bit).

As far as headroom goes - headroom is a term from the days of analog mechanical recording to mean how much of the signal that we want, exists above the murky white storm of the noise-floor.
In this age of digital recording and processing, the introduction of errors or artifacts into the signal is the mangy beast we fight. When that white haired scientist makes a bad choice we end up with an artifact (it sounds like digital noise or crunchiness or harsh distortion, try out the built in effect Redux) and the more we process and combine and reduce the more errors we gather.
The way to avoid these errors is to have a clearer picture of the sound in the first place and to use more precise processes to change it - 64Bit is that more precise tool than 8,16 or 32 bit.

Hope that helps you make your decision, I think the other improvements in Live 7 are just as important as the 64 bit processing. The tempo nudge buttons to me as a performer who works with other external beat generators, are worth 1/3 the upgrade price...... or .32 of it at least!

I just upgraded to version 7.0.1 and I can hear the difference vs. version 6. My assumption is purely subjective, based on what I'm hearing, but hey if we as musicians can't detect subtle differences in audio fidelity then who can? The reverb and delay tails are much cleaner and discernable. I'll leave the quantum calculations to the engineering types.

membrain > i know I said i was finished with the topic and im very tired now so must go to sleep soon but before I go :lol: what you say is based around the science and add to this the marketing campaigns software companies have to do I have to ask where is the human side to this. I have said above I hear no difference at all and it isn't as if I started with music just yesterday and believe my ears are as good as anyone else. I think what I said about 25 year old programmers has a lot of validity because who made them the defining authority on what makes better sound. I know this may be sounding like angry man critical of programmers but Im not like that im just asking direct questions.

I can remember a time when a designer of hardware would answer all relevant questions but today's designer seem to be very quite on many aspects of the tools we musicians use, I also think theres a very elevated status given to the people by and I question that, yes I certainly do and its something I have only recently began to think about because of the large amount of awful stuff out there today.

just dont buy everything Im being told by software companies today. They can an quote me figures from now until the end of time but I must trust my instinct - ears - and humanness. Programmers deal in numbers and equations and so on but have they actually ever worked on making a full song or in a studio. I think most haven't judging by the extremely poor designs of much of the software that seems designed to dazzle the users eye sight more than anything else and actually gets in the way of creating music. I dont mean all of them of course but Im seeing a lot of software and plugins that have no musical basis or use in real projects but due to marketing they are purchased.

But back to the discussion. How is a 16 bit sample from a CD going to benefit in any way from 64 bit processing. I will wage it wont. How is someone's vocal recorded through a sub 1000 pound interface going to benefit, again I will wager it wont. Now, if the benefit is there by recording 32 bit audio at 96khz then they should tell us these things but even then I have recorded at 96khz and heard no difference at al. In saying that it could very well be the audio interface I use for recording external sources. But I guess the reality is the amount of power needed to do this would be so much we would all have to have 8 core computers and obscenely fast hard drives. But that will happen and it will be another mass of upgrades and sales for the software industry.

I think the next time around will be 128 bit processing and again we all have to go through the process of upgrading OS systems - plug-ins - Software and on and on we go. When will it stop, never is my guess. But a few people like myself are questioning this whole process because quite honestly, nothing beats one of those high quality expensive Neves or SSLs but yet on paper any daw has a better signal flow. Like I say I just don't buy it, I dont hear any difference and I am going to trust my ears even more so these days. :wink:

Again your talking of plugins which may have been recoded. My whole point is asking if the audio engine is better as is the claim because of the 64 bit engine.

I must go and sleep now. I did no music tonight :lol:
