<div dir="ltr"><div><div>Hello,<br><br></div>My experience is partly similar to what Charles mentioned: an external soundcard can be much better in S/R ratio (both Brownian noise of the preamp and specific frequencies produced by power supply). I would not say that noise is less noticeable in live performance though - on the contrary: it is heavily amplified on the pa system, more than in a home environment. Furthermore, in live performance you need a directional mic and these are less sensitive than omnidirectional mics, so you need to amplify more and S/R ratio gets worse. <br>
<br>For this reason I bought myself a nice audio interface which works with Linux, a Mackie Onyx Blackjack. Not expensive, two channel mic/line/instrument with phantom, low noise. Later however, I noticed Panasonic unidirectional electret capsules which can be directly connected to a built-in computer sound card with mic input. Sensitivity is less than omnidirectional capsules but better than dynamic or condenser unidirectional mics. The Panasonic capsule is very sensitive to plosive mouth noises and initially I thought they were useless. But with good wind protection (imitation fur) it works nice. The type of this capsule is WM-55A103. My friend bought them from Digikey but it seems they're out of stock now, obsolete they say! They can still be found from other sources. <br>

I will use my wireless VHF SHURE microphone (I know it is old). The
original is a headset, but, for beatbox, I use a SM-58 connected to
the same trasnmisor. It sounds different, so, the SM-58 jack has a
resistor to turn the gain down and an EQ in PureData, to make it
sound like the other.<br>

I will buy the cheap soundcard (ARS $200). I understand what you
say, but it has some benefits:<div class="im"><br>
<br>
- I care the notebook audio-out jack. USB is more resistent for
pluging and unpluging. I (this) summer, I work in a park and I do
what this video shows, EVERYNIGHT:
<a href="http://www.youtube.com/watch?v=oNUZULR7k18" target="_blank">http://www.youtube.com/watch?v=oNUZULR7k18</a><br>
- I have more inputs and outputs (for future features).<br>
- Maybe, I avoid noise in the line (for the moment, I don't have
it... but I think it depends on the power line of the location).<br>
- Sometimes, I do record some samples... it will be usefull for
that.<br>

<div>Keep in mind that you'll need very low latency (less than
20 miliseconds) for your application. I'm not sure if this is
affected by the sound card or not. All of the audio processing
happens on the CPU, but maybe the buffering stages for the
sound card add enough delay to add latency... could somebody
with more familiarity chime in here?</div>
</div></div>

For now, I have 5.8ms of latency. It's very good for me. If you are
saying that an external soundcard would add latency... more than the
internal, so, it is not good!<br>

<div>Hi Mario<br>
</div>
<div><br>
The number one reason for having an external
sound card is noise isolation. The card's
proximity to the power supply and
motherboard are bad for EM noise. Also, a
computer power supply and a good audio power
supply for recording have much the same
relationship--there's more noise in
switching electronics.<br>
<br>
</div>
Next, there's the size constraints. You'd
have a hard time adding all the connectors for
a large number of channels on a card which
plugs in to your PCI(e) slots.<br>
</div>
</div>
</div>
</div>

</div>
It's ok, I have a notebook: 1 plug out, 1 plug in.

Third: there's not as great a need for
bandwidth for audio as there is with video.
Video cards need all that PCI(e) bandwidth.
Audio doesn't. It's a relatively small amount
of data. Of course--I think USB and firewire
really don't have enough bandwidth for good
scalability, but that's another discussion.<br>
<br>
</div>
But... what are you doing with it? You have
different requirements for recording and for live
sound. Live sound: just do it up. No one will
likely notice.<br>
</div>
</div>
</blockquote>
</div>
Live sound is my purpose. Mic-in looping-station and
multieffects system (following the steps of Beardyman and
his Beardytron_5000). But, sorry about not understanding
your expresion (english is not my native language)....
What do you mean with "just do it up, no one will likely
notice"? Should I buy it or no one will notice the
difference? I think you mean I should...
<div><br>
<blockquote type="cite">
<div dir="ltr">
<div><br>
If you're planning on recording something on just
2 channels on the built-in sound card, keep in
mind that your dynamic range will be pretty bad,
even if you get a good pre-amp in the middle to
take the most advantage of your range. You'd much
rather have an external sound card with some
adjustable analog pre-amps in the box.<br>

About the soundcard I post, the Encore 7.1 ENMAB-8CM (<a href="http://www.encore-usa.com/ar/support/ENMAB-8CM" target="_blank">http://www.encore-usa.com/ar/support/ENMAB-8CM</a>)...
it's really a china generic useless card... or it's good
for starting? It has no analog pot.<br>

I know that Pd is processing on CPU and I don't

Is there any benefit of using one?<br>

I know that this USB soundcard is not a very

What's your opinion?<br>
