• continuing audio captures

    From Jake T@21:1/5 to All on Sat Dec 11 09:19:07 2021
    So, I've been continuing with the mainly coyote audio captures, weather permitting. The coyotes definitely have preferences for when they howl,
    at least in my area, and I've quickly learned them.

    Trying to get the correct "inverse EQ", due to the dish, has been a
    challenge, even more so if any noise reduction is done, but I came
    across a surprisingly free plug in called TDR Nova GE. Well, not really
    free, but at least the demo doesn't have any time limitations. It won't
    allow you to save settings, but this really doesn't matter for the small
    amount of audio I'm working with. Only issue with TDR is that I can't
    seem to export a treated file from within Audition multitrack. It just
    exports like I never used the plug-in. Now if I work directly on the
    wave file itself with the plug in, it will export, but it needs two
    instances open, as far as I can tell, to be able to use the EQ match, so
    I've just been writing down the six band settings it recommends and then inputting them manually for a single instance with the wave file. Maybe another demo limitation, not sure, but with the small amount of audio
    I'm doing not too much of a drawback. The big thing is that it gets me
    a lot closer to a proper EQ as I can use a known, good coyote audio file without any coloration, and then apply its EQ to the dish recorded file.
    I also have their SlickEQ installed, but haven't tried it much yet.

    I was hoping someone could answer the Zoom H2 questions I have from the
    other thread. I'll be embarking on the remote, permissive property set
    up this week but I won't be able to monitor the H2 as frequently as I
    can at home. I'd mainly like to know how long a set of Eneloop AA's
    would last recording with "compressor 1" in 44/24 format? It seemed to
    go for at least 5 hours at home, but I ran out of time to go further.
    Also, what happens when the batteries run out, would the unit shut down automatically and would it keep or not keep or corrupt the SD card files?

    Thanks.

    My experience of the H2 suggests a clean shut down when the batteries
    expire. As it closes down under the control of the battery level sensor,
    it stops writing data to the card, writes the file header and other
    details for the current file to the File Allocation Table, then turns
    the machine off.

    Thanks! That's a big plus. Now if I can figure out maximum battery
    life with these Eneloops. They are the standard ones that are, I
    believe, 2000 mA/h. 24bit/44Khz, compressor 1 and 110 gain. I was
    tempted to try the Eneloop "pro" versions but I understand that they
    might actually drain more quickly.

    You use Audition, yes? The FFT filter is perfect for the inverse
    equaliser. That's what I used. Apply it from 500Hz to 5kHz (a 20dB
    total drop across that band), and drag it all the way down outside
    that range.

    Thanks. Yes, I could do that, in fact I was first doing that until
    trying out the TDR Nova plug in.

    Well, the batteries have been going for six hours with the
    aforementioned settings, keeping my fingers crossed for however much
    longer. I also switched out for a 32 GB card. Was surprised that it
    worked.

    The H2 is compatible with SDHC cards, which have a maximum size of 32GB.

    Bigger cards are SDXC, which is not hardware compatible, and will
    probably wreck the card.

    When you are updating the firmware, you must use a standard SD card,
    with a maximum size of 2GB.

    I don't think I've ever updated it. Any advantages to doing so? One
    thing I wish is that a USB power bank could be used and allow it to
    operate normally. Only thing that happens is that it waits for the
    computer for either use as a mic or storage.

    There are a couple of minor bugs and interface niggles that the update
    gets rid of. The full story is here:-

    https://zoomcorp.com/en/us/handheld-recorders/handheld-recorders/h2/h2-support/

    The version history is down towards the bottom of the page and tells you
    what niggles have been fixed with each version.

    There are also ASIO drivers for your PC if you don't already have them
    which work better than the Windows drivers that you are probably using.

    As for using external power, if I remember correctly, the mains power
    unit gives 6 volts DC to the socket on the H2, so you may find that if
    you make up an adaptor from a USB A plug to the correct size and
    polarity plug for the power socket, 5 volts will do the job. For a few
    dollars extra, you or your favourite electronics repair guy can make a
    cable up with a voltage converter to give you the correct voltage for
    the H2, then, the sky is the limit, as you can get a phone charging
    power bank that will run it for 24 hours or more.

    Thanks. I think I will hold off on the firmware update until after I'm
    done with this remote set up. I now have permission for the next week
    and don't want to jeopardize it if the firmware causes issues. Not that
    it would, but just don't want to take chances for now.

    Well, I found out that, with the fully charged Eneloops, with the H2 in
    the refrigerator to simulate the cold, I get about 8.5 hours. Good
    news for my purposes meaning that I won't need anything extra. I was
    tempted to order and try the Eneloop pro batteries, but they only seem
    to offer just a tad more mA/hr so just not worth the extra cost.

    The H2 socket uses 9V. I've already been using it with a 12V lithium
    battery with a converter to get 9V. Works ok and could power it for
    several days, but there is a connection issue somewhere and
    unfortunately until I repair it, I can't trust using it remotely. The converter was one of the cheap Chinese ones and it looks like the screw
    down wire connectors have become loose causing intermittents. Just one intermittent is enough to stop the H2. Maybe if I had batteries in the
    unit itself, they wouldn't let that happen in which case I would
    consider using the outboard power pack.
