    Tascam portacapture X6

    EiN of -125 dBu is very good, almost as good as my (affordable) reference standard of -127dBu for the ZOOM F3, F6 series. But I would suspect that did not include the attached mics. You would need to use a separate low noise mic, (as Mono suggested above).

    New field recorder

    Thank you, Jon, for those observations. It's because of the typical handling noise that for me, field recording means setting up mic and recorder on a tripod and standing back/walking away. More of a planned recording session. I wasn't thinking of the "point-and-shoot" option which might be more...

    New field recorder

    Unless you need integral mics as well as mic input connectors, why not choose the Tascam FR-AV2. That model appeals to me because of it's relatively large display screen, and has very good EiN figures. I don't know about its battery life though. Personally I use a ZOOM F3, which I bought before...

    Low Frequency recording help needed

    I also have a DiY SASS head (if in doubt, Google it), fitted with AOM5024 capsules. Very sensitive and low noise, but definitely not directional. Recording on a ZOOM F3. If your target is only 10-20 metres distant then I'm not sure why you would need a directional mic anyway ?

    Low Frequency recording help needed

    I have recorded the call of an Australasian Bittern, which has a fundamental frequency of approx 140 Hz. I used a parabolic mic (with AOM5024 capsules) on a ZOOM F3 recorder. The bird was distant, the call was faint, and in theory below the frequency range of the parabola. But it still recorded.

    Microphones AOM 5024

    Like talking to a brick wall. Does anyone else know what a "sound trap" might be ?

    Microphones AOM 5024

    I use them in a parabolic mic, but I don't understand what you mean by a "sound trap".

    Article on Parabolic Microphone Gain

    Very interesting, and very clever.

    Article on Parabolic Microphone Gain

    Aha, that's better. Now another challenge, following your equations. I notice you have a Wildtronics parabolic mic. Something that has mystified me is the "barrier disc" in the centre of the parabola. Can you explain why one would place a disc there ? It seems to be obscuring the incoming sound...

    Article on Parabolic Microphone Gain

    Really interesting. The animated images are very useful in understanding the text. However, in my download, the equations were not reproduced, just a gap in the text.

    DIY Stereo Field Dish Microphone (WIP)

    Looking on the bright side, you've probably saved a fortune in shipping costs. As an alternative you could purchase this budget priced parabolic mic, $43.39 AU with free shipping. Downside is the diameter, and no tripod mount. Upside is total cost includes headphones, electronics, 'scope...

    Just checked that UK link, the dish is listed again at the original price 69 GPP. https://www.parabolicmicrophone.co.uk/products/parabolic-reflector I haven't seen a better price for reflector/handle.

    Sound clip

    Thanks for the positive response. My new H1e arrived yesterday, but then I discovered it takes micro SD cards, which I don't have. Back to on-line ordering, should arrive tomorrow, and then I'll do some testing. Cheers Alec

    DIY Stereo Field Dish Microphone (WIP)

    You are making great progress. You could shrink the bulk by using eg, 32mm plumbing bits. Then a 32-40mm sleeve for the drill handle to clamp on. The hardware shop might even do a trade, 32mm for your 40mm parts.

    Sound clip

    Thanks Jon, I was thinking of posting a clip illustrating the H1e recorder attached to a parabolic mic, both items of current discussion on this forum. But if it's going to received like a lead balloon, then I won't bother. Cheers, Alec

    Sound clip

    Just wondering if is possible to post a sound clip (bird song) on this forum ? Or is it frowned upon ? If OK, then is there a recommended format ? file size limit ? etc ? Cheers, Alec

    That's a very interesting analysis of the paraboloid, by Michael Hurben. Thank you for that link, Cheers, Alec

    DIY Stereo Field Dish Microphone (WIP)

    A few days ago, when the dish was in stock the price tag was 69 GBP. Perhaps "Sold out" is another term for "price rise coming up". But hopefully I'm just being pessimistic.

    DIY Stereo Field Dish Microphone (WIP)

    Some insects, like wasps, are not very sociable, and some, like cicadas, won't stay if you get too close. The parabolic allows you to get acoustically close at a safe working distance, while at the same time reducing surrounding noises. and, another thought, If the Wok gets too much, then this...

    DIY Stereo Field Dish Microphone (WIP)

    Just thinking, laterally. You have been drawing your "ray diagram" with parallel lines striking the face of the parabola. This would be reasonably correct if your target (bird) was a long way from your parabola, eg hundeds of metres. But what if the bird was much, much closer, just a few metres...

    Have you read this DIY parabolic mic project from Tom Benedict ? https://tombenedict.wordpress.com/2017/12/21/diy-stereo-parabolic-microphone/ You may pick up some ideas for a handle, (and other things too).

    Have anyone tried the new Zoom H1 essential?

    I have just ordered a Zoom H1e to use on my newly acquired parabolic, refer, MICROFONO PARABOLA - PARABOLIC MICROPHONE Plug In Power /XLR 25-35-53cm diameter | eBay The Zoom F3 was higher on the wish list, but money was an issue. I'm aware of the H1e's not-so-good Ein level, but I'm hoping the...

    Zoom M-series Sound Recorders

    Is anyone thinking of adding one of these to their collection? The part that appeals to me is their 32-bit recording, having just tried to record a thunderstorm with a standard Zoom H recorder, and being blown out by an unexpected overhead thunderclap. Yeah I know that's not strictly bird song...

    Reasonably priced recording device.

    Agreed, off-topic a bit, but while I have your attention. I have done some stereo (3D) photography, stills not video, and in particular hyperstereo with telephoto lenses. I was sort-of hoping there might be some analogy with hyperstereo sound recording with "tele" parabolic mics. But the...

    Reasonably priced recording device.

    My recommendation is based on the idea that this particular parabolic mic is basically a do-it-all device. Just pick it up, aim and push the record button. Definitely not a kiddies toy. Albeit with limitations of recording time, but at a very realistic price. Note, you can connect it directly to...
