Re: Wind noise question

2010-11-08 Thread Joe Paton

Dave,

You could try removing certain frequencies, but 
the trouble is that the wind noise covers quite a wide frequency band range.
Then of course, the sound of your voice will 
inevitably change as you reduce frequencies.


It's a learning curve, and the olympus range are 
not tollerant of wind noise, even human breath on 
the nics.  A wind shield could save this in future.

Ok, I admit to being kind of disheartened at my apparent inability to record
decently in hostile environments.

The other week I was outdoors on boats and para-sailing with Olympus DM520
happily in hand.  Frankly the resulting recordings sound awful because of
the wind noise.  Is there anything I can do with Goldwave to reduce this
without killing the rest of the recording?  Is wind low or mid-range?  I
shouldn't be kicking myself on my birthday but I am; I expect better of me.

I've not experimented much with MP3 files though logic would dictate that
the rate of writing would be smaller, the way I look at things regarding the

Zoom H1 is that I need not bother with MP3, after all! I have a computer
which probably does a far better job than the Zoom H1 does at MP3 encoding

 Dane, you mentioned wav files.  How about whilst using MP3's, and the

 There are many of these weird things I use the induction loop coils in a
 hearing aid for.

 I can hear  the hard disk of my iriver hard drive booting up for example.
 And my cell phone to know if it's starting up or not.

 If a normal hearing person can get hold of a small amplifier with an
 induction  loop built in,  you will be able to check all kinds of
 interesting things.

 Hi!

 Now this tip isn't going to be for everyone as not everyone wears hearing
 instruments which can be used with induction loops but if you do? Well
 here's a handy way to use your instruments to great effect when sorting
 out
 one of the very few functions of the Zoom H1 which isn't accessible.

 I'm talking about the Bit and Sample rate of the file you're recording,
 this
 is changed in Standby mode by using the fast forward and rewind
 buttons,
 rewind takes you back through the cycle whilst fast forward takes you
 forward through the cycle of bit and sample rates.

 When recording using Wave Broadcast format you cycle through 44.1KHZ 16
 Bit,
 48KHZ 24 bit and so on right the way up to 96KHZ 24 and back to 44.1KHZ
 16
 bit so how to tell where you are.

 Well turn your instruments to pick up induction loops and put the
 recorder
 near them.  Now start recording, you'll be able to hear the recorder as
 it
 writes to the SD card and the slower the rate of writing then the small
 the
 sample size, 44.1KHZ 16 bit has the Zoom H1 writing to the SD card about
 every half second whilst 96KHZ 24 bit has the H1 writing to the SD card
 every sixth of a second or so.

 Just thought others may find this helpful as I do, still haven't worked
 out
 a way to set the date and time for date/time stamping of recordings but I
 have to admit to not trying too hard, after all! one can change all that
 when the files are copied from the H1 to your computer.

noisy and low quality mp3 audio lectures cleanup

2010-11-08 Thread E.
	I have received a MP3 file of a lecture where the speaker did not 
speak into the microphone.  Can anybody think of utilities or 
programs I might use to make the sound more audible?  Also, are there 
utilities I can use to filter out hum and background noise?  The 
audio files I get are sometimes not in the best shape.


I have Windows Media Player on my system. I use the latest version of 
Window-eyes on an XP machine. Thanks for any suggestions.

Goldwave can filter stuf out. Select a little clip of the background
noise onto the clipboard and then tell goldwave to filter that kind of
noise out.
