Hi Pete - Post your questions in the forum.  We finally have reasonable internet, and will be stopping by more often. :)

Forums pretty inactive. What's the best way to ask some easy questions re Audacity?? ;)

A/B Mic test - DR05 Vs Condensers
« on: August 24, 2013, 05:06:29 AM »
Ok, so here's a quick A/B test.   MP3 attached.
 
This test is to compare the difference of mics,
 
Using the two identical DR-05 units, but with different mics.
 
1 recorder is with the mics that come with DR-05  (L & R are fixed at about 3 inches apart.)
1 recorder is with electret condensers plugged into the DR-05 (the condensers are housed in two parabolas so they are spaced about 12 inches from centre to centre)
 
so the MICS are the only difference for this test.  levels are very close to matched too.
 
the two units are placed on a chair - one above the other ... the mics are picking up identical sources.
 
The identical event is played one after the other ... you'll hear the difference of mics after one or two listens, I'm sure.  Sample 2 is the parabolas.
 
If you bring the file into your DAW, you can see that both files are stereo, but one is 'clearly' more stereo than the other.   
 
Setting up the parabolas feeding the DR-05 may be a cool move... nice to have the option.
 
I love how you can close your eyes and actually pinpoint where the voice is coming from in the stereo soundstage.  8)

I'll have to try an A/B test out on the water too, for a more accurate depiction of the 'stereo' field.

Apologize for dredging the older thread but just arrived at this great site.

Currently I'm just using a DR-05 for "bedroom volume" recording of guitar and - as long as I let the amp do the work & keep the DR-05's internal gain down - things seem fine.

I was wondering about some specifics on the condenser mic you used, especially as to how close (or far) the mic was in terms of the input impedance the DR-05 wants to see?  Also what was involved in the physical interfaces involved.

And yeah, the field & depth provided by the electrets is hugely better than the built-in mics on the DR-05.  Dramatic recording so thanks for that effort.
Thanks.

Hey Wes, ( sorry for the late-ish reply, as I've been on a field trip this past week )

Yeah, the DR-05 is a good personal recorder.  I'm really enjoying the two units I have.

You're asking about mic to source distances etc.... and I'd say that the Tascam DR-05 should be able to handle reasonably loud sound pressure levels without any degradation of the signal, when the 'input' level of the recorder is set low enough to not allow any distortion to occur.  Finding that sweet spot is key, or to at least not exceed the upper limits of what it will take.
I find that if I aim at recording a 'loud' source about 6 dB lower than I actually want it, this leaves me enough headroom later when I import the track into a DAW (audacity, or Reaper, etc) where you can then adjust track levels etc from there, to the get the mix you want.

As for hooking up external mics to the DR-05, ... pretty simple, plug in 3.5 mm mic jack into DR-05 'external mic' slot, and in my case, I have to set the 'mic power' to read 'external' so it doesn't use it's own internal pre amp power - but instead uses the pre-amp power I supply from the condensers.  Once it's set, and record input levels are set, you can simply forget it... if the conditions remain the same in subsequent recording sessions. cool.   8)

As for proximity of mic to source and levels to choose...  When I'm in the field, recording distant or ambient sound scapes, I use full mic gain settings, which does add some 'noise' to the signal - as in background 'air' but the internal system noise is still pretty low, considering it's at max output.   I clean this up during mix and mastering.  :)

For CLOSE to source recording, such as a guitar amp, or a very close bird call or for lightning strikes, I must crank down the mic gain signal on my pre amp to -20 dB (boost off) .... and I also need to reduce gain of the signal on the record level going into the DR-05 as well.... reducing the signal til I reach approximately -12 to -18dB ... which allows for 'spikes' to happen without the risk of going over the top and 'clipping' the signal.... as the DR-05 does NOT handle clipping well.... the signal will be cooked if this happens. So lower signals can always be raised in the DAW later, but cooked signals can never be repaired by lowering them later.  8)

If you want I can put a quick vid together showing you how I set the Tascam DR-05 up for loud signals (like a guitar amp etc) and how I set it up for recording with the external mics and pre amp.   :)

I hope this helps, (would love to hear some of your work that you've recorded too, so post a quick sample here, or a full song in the 'listeners' section.)
 :)

Thanks very much Glenn for taking the time.  I guess I didn't glom onto something that should've been obvious to me; with the condensers you're running a pre- anyway.  (When I said "how far" I actually meant "how far different in impedance was the mic to the DR's input.  So, again, shame on me.)  So the DR's 25K input impedance (far away from a regular low-Z mic) is just handled by how you send it from the pre- to the DR.  (Headslap occuring at this end.)

Thanks for the nice note also.  I'll dig around and see if I can come up with a DR-recorded cover tune worthy of posting as well as the one original I've done.  Enjoy playing & mixing but my brain (probably for betterment of all) doesn't work like some of my compatriots in instro-surf who are compositional monsters.  But it's fun, so it's a bit like feeling free enough to simply draw/paint for my own enjoyment.

Again, thanks for taking the time.  :)

In August I'm headed to an evening cruise that has 2 great surf bands (friends as well) so I'd better acquire some tools to take the (better) audio from the DR and marry it up with any video I shoot.  I'm sure there are tools for that, else youtube would be out of business.

yep, the DR05 will make a good little companion when you shoot vid... I'm really basic with vid ... so I usually just shoot the video with recorder going, and 'slate' the video/audio by stating what I'm recording, and OR simply make a hand clap so video shows what the audio hears... then you just sync em up later, on your video editor by sliding the audio forward or backward a few frames.   I'm using Trak-ax which works pretty well for my basic needs.  8)
As I said, I'm a novice when it comes to video, so I'd be happy to share and learn more .. I think there's a place for that in here somewhere... lol  if not, just make one.. lol  :P

... and that's cool about playin' surf tunes... I figure, do what you enjoy, and if others happen to like it too, so much the better. I'm looking forward to hearing your music.

Thanks Glenn; I'll give TrakAx a look.  I'm always up for cheap or free.
