Amplitube 2 Jimi Hendrix RELEASED this month!!!

[warren]

someone asked earlier about how the m-audio jamlab compares to the stealthplug? the m-audio can do 24 (or 16) bit at 44.1/48, while the IK is limited to 16 bit. plus the m-audio is anywhere from 30 to 40 US dollars cheaper.

i'd say the winner in that race is clear.

i think the reason why you don't hear much about these two products is because they're basically just a cheap soundcard/di box. most guitar players into home recording already have a great soundcard and preamp/di that far out-perform these things.

*btw - the dongleless ampeg svx update HAS BEEN RELEASED THIS MONTH!!!

actually i don't know exactly when it was released but i just checked their site and it's up. i'm a checkin' it out now.

So, can someone finally *please* tell me about reallife latency figures of that Stealth thing? And I'm not talking about buffersizes but overall in-to-out latency measured manually or via AU lab or whatever.

I seriously don't need all that additional loops and whatever. I wouldn't even need Amplitube Live (even if it's surely nice to have), but what I need is *truly* small latency figures, and most USB interfaces suffer from a more or less horrible amount of (usually undocumented) additional "safety" buffers, which is especially true for CoreAudio (which, btw, seems to be quite a lot worse than ASIO, even if Apple is trying too fool us into buying their "low latency for everbody" bullshit).

Does anyone know if the stealthplug can be used with USB speakers?

[Sascha Franck]

Squids and stag, am I right in assuming you are just too freaking lazy to do a reallife latency test?

Does anyone know if the stealthplug can be used with USB speakers?

Sorry, I don't "know", so just adding more second-hand information here:

The specs do not say that it offers WDM drivers. I checked around the web, and no WDM mentioned anywhere. That also explains why ASIO4ALL doesn't work, since A4A is a layer over WDM.

If it is ASIO on PC, the answer is no:

USB speakers are literally external soundcards, boxed up along with the speakers themselves. That makes them a whole separate I/O device. Since the ASIO spec does not allow for multiple devices, you will not be able to use the Stealthplug along with USB speakers.


If you are using CoreAudio on Mac, the answer is yes:

Mac's CoreAudio spec allows you to create "aggregate" devices, which essentially create a new unified driver so that you may gang multiple devices together and have your apps treat them as one device. You can aggregate your USB speakers and the Stealthplug together, and then use the speakers as output and Stealthplug as input.

Hope that helps,
Greg

ASIO4All would allow for such things as well, but I doubt it's working as well as OSX' aggregate devices. I'd expect higher latencies and CPU consumption, probably coming along with record offsets.

[Lunch Money]

Right, but as I mentioned, there don't seem to be WDM drivers. Which means ASIO4ALL won't work. ASIO4ALL uses WDM.

[Sascha Franck]

Hm, doesn't ASIO4All work with almost any MME driver?
I mean, even the Realtek thingy shows up on my laptop. To me it seems ASIO4All is simply labeling them "WDM".

Squids and stag, am I right in assuming you are just too freaking lazy to do a reallife latency test?

A project that opened with 60% CPU usage with the Ozonic set at 512 samples, opens with Stealth set at 576 samples 48K at 80%, i guess if the samperate was the same the Stealth could give way better results. BTW the samplerate cannot be changed inside C4, to go on working on this project, i migth had to resample or stretch all audio files.

it can go as low as 2ms latency, reported inside C4, with the 96 samples buffer size, the lowest possible.

The hardest presets, CPU wise, on AT2 are called without any trouble with 96 sample latency setting.

WMP can't use Stealth as a playback device so WDM, MME are not there. oh WaveLab doesn't connect with it too.

[Squids]

Sometimes I am busy Sasha! Haha. But, I am traveling to Germany next week... and will probably bring my Stealthplug as well! How cold is it over there?

We should have a KVRian beer drinking fest on Sat in Hamburg if anyone is up for it. I won't win. I am used to American Bud (ie. water).

[Sascha Franck]

So stag, have you done a real latency test? Like recabling your outs to your in?

Squids, it's actually quite warm right now, between 10-14 C° during the day. Too warm, to be honest, nature's flipping out and if it doesn't get any colder soon, we'll be having tons of insects next year.
Unfortunately I can't make it to Hamburg on saturday. Will be gigging.

Hard to do that kind of latency test with i\o like Stealth.
I Just checked inside Cubase Device Manager.

off course if the samplerate was at 44.1K then instead of 2ms probably it would be 2.3ms.
The input and output latency are the same. MIDI timing should be no problem i guess.

No, all you need is a cable connecting in and output, then use this tool (no installation required):

Speaking of input methods, what are you all using as guitar computer interface(s)?

I used to plug my guitar into my soundblaster crappy card and the sound would be unlcear and muddy. Now that I am using podXTL as my input method and get clean signal to my VST effects, the sound is a lot better than before. The only drawback with this approach under ASIO is that I cannot use my monitors, and I have to use headphones instead.

I tried Asio4ALL to aggregate IOs but the latencies killed me. I would be able to get it to 12ms, but the lag got very distracting.

I have the Centance test, it can be calcuked with the "Ping" function in Cubse.
The card has a input cable with a 1/4" jack and the output is an 1/8" headphone input.
