Anyone here using the Velodyne SMS-1 mic with Spectrum Lab?

I purchased a SMS-1 with the mic kit (used) a couple of weeks ago. It helped me a lot to EQ my sub. But now that everything is set and running great on my SVS PB12-Plus DSP; I am just wondering if it can be used with Spectrum Lab and if I can use a XLR to USB cable to connect it to my laptop.

Any input will be highly appreciated.

The SMS-1 mic (rebadged ECM8000) works. I compared my 5 years old SMS-1 mic to another calibrated mic (Earthworks M23) and the discrepancy below 2kHz was less than 1-2dB.

I have every reason to believe that at home, this movie will kick butt.

that's good to know - because I'm probably going to be watching it at home.

Clipping is a form of waveform distortion that occurs when an amplifier is overdriven and attempts to deliver an output voltage or current beyond its maximum capability. Driving an amplifier into clipping may cause it to output power in excess of its published ratings

Overview of clipping
When an amplifier is pushed to create a signal with more power than its power supply can produce, it will amplify the signal only up to its maximum capacity, at which point the signal can be amplified no further. As the signal simply "cuts" or "clips" at the maximum capacity of the amplifier, the signal is said to be "clipping". The extra signal which is beyond the capability of the amplifier is simply cut off, resulting in a sine wave becoming a distorted square-wave-type waveform.
Many electric guitar players intentionally overdrive their guitar amplifiers to cause clipping in order to get a desired sound (see guitar distortion).
Amplifiers have voltage, current and thermal limits. Clipping may occur due to limitations in the power supply or the output stage. Some amplifiers are able to deliver peak power without clipping for short durations before energy stored in the power supply is depleted or the amplifier begins to overheat.
Amplifier power ratings are typically established by driving the device-under-test to the onset of clipping, to a predetermined distortion level, variable per manufacturer or per product line. Driving an amplifier to 1% distortion levels will yield a higher rating than driving it to 0.01% distortion levels.[1] Similarly, testing an amplifier at a single mid-range frequency, or testing just one of two channels, will yield a higher rating than if it is tested throughout its intended frequency range with both channels working. Manufacturers may use these methods to market amplifiers whose published maximum power output includes some amount of clipping in order to show higher numbers.[1] For instance, the Federal Trade Commission (FTC) established an amplifier rating system in which the device is tested with both channels driven throughout its advertised frequency range, at no more than its published distortion level. The Electronic Industries Association (EIA) rating system, however, determines amplifier power by measuring a single channel at 1,000 Hz, with a 1% distortion level—1% clipping. Using the EIA method rates an amplifier 10 to 20% higher than the FTC method, at the cost of audio fidelity.

Clipping detection
Clipping in a circuit can be detected by comparing the original input signal with an output signal that has been adjusted for changes in applied gain. For instance, if a circuit has 10 dB of applied gain, it can be tested for clipping by attenuating the output signal's gain by 10 dB and comparing it to the input signal. If the circuit is driven into clipping, the attenuated output signal will show less voltage in the comparison. The electrical offset between the two signals can be used to illuminate clipping detection indicators, such as a red LED, and can be used to decrease the gain of a preceding circuit so that the level of clipping distortion can be limited

Thanks Ken!

It is great to hear that I should be able to use this mic. Now, can I use a simple XLR to USB cable to hook it to my computer (Windows XP) or do I need something like Icicle XLR to USB Mic Converter or Tascam US-144MKII?

I have a HSU VTF3 MK4 and it already shakes my butt, would a buttkicker really make an improvement in my theater?

Is your theater on a concrete floor or a "suspended" floor?

Its on the second floor in my house.

I appreciate the response! But I meant on the graph! I'm assuming its the chart on the right with "blocks"

Saw Contraband on BD and pretty disappointed with the LFE. Some pretty good midbass energy during the Panama shootout scene but that's about it.

I use a mic preamp (with phantom power) and soundcard between mic and PC and have no experience on XLR to USB mic converters.

Out of curiousity I once hooked up the Galaxy CM-140 (SPL meter) to the soundcard (without mic preamp) and found out that the noise floor was too high.
On the other hand, Icicle XLR to USB Mic Converter seems to be promising with 48V phantom power compared to plain SPL meter.

If you set it up right, yes.

Hello all,
I could be mistaken but I don't remember seeing Super 8 on the list. After watching about half of it last night (I'll finish it tonight after work), it had some pretty good bass moments, could be a solid 4 stars. What do you think?

the grey...plane crash was fun, but that was about it...the wind created some rumbling.

I would agree...tho many disagreed due to the lack of extension...I thought the dynamics and mix of this movie was simply awsome...and enjoyed the low end

The train crash scene is awesome.

Use the Search this Thread function and you will see a lot about it. No much really low frequency but that only shows you do not really need it to be well done.

The grey? Solid 4
post #3859 of 16207
Just watched UA and Battle LA and agree they both are on the 5* list.....both big thumbs up!
post #3860 of 16207
UA, 5 stars. We were laughing at one point from the pure LFE joy
post #3861 of 16207
I don't see Real Steel on the list anywhere. I thought most of those fighting scenes were quite impressive.

I loved Battle Los Angeles too. Despite the film's terminal stupidity, it looked great and sounded better. Great fun!

Just watched Chronicle, I thought it was done very well in the LFE department especially when listened to at spirited levels.

I agree! Thought it sounded great. I really liked the film itself as well!

Yea I went for a rental not expecting much but it surprised me also! This is one of those flicks that just didn't get that much recognition I think due to all of the blockbusters released recently in the theaters. Well worth a watch.
post #3867 of 16207
Is Chronicle worth a blind buy or should I rent it first befrore buying? I did not think much of the sound in Super 8. The dynamics were very good but to me the LFE was not that impressive. Gonna watch Underworld tonight. Real Steel was good but not more than 3.5 stars. I still think Transformers DoTM is a solid 5 without a doubt. What about 5 Days of War? The LFE was fantastic.

I blind bought Chronicle and like I said wasn't disappointed.

I watched Underworld:Awakening last night.........it is raucous all the way through

I agree. I watched it again last night. I have to say it has one of the cleanest soundtracks I have ever heard. Plus, the Crowson system really helped put it over the edge for me. It made it more fun for sure. I can't wait to watch TDK again with the Crowson.
