I bought a new microphone.when i begin recording with audacity the spectrogram shows a big noise caused by the microphone.and if i listen the result i hear a big noise and my voice is very low.microphone settings are ok.what can I do ?
Select a short clip of the noise and post it on the forum so we can hear it. Use good quality MP3, not WAV.

Then, while we’re chewing on that, you can fill in the information from the pink band at the top of this thread. Also include the maker and model of the microphone.

If you are using a laptop, scratch on the microphone grill or tap it with your fingernail to make sure you are recording your new-external microphone and not the laptop’s built-in microphone.
here is the file.i try to scratch on the microphone grill and it records.
microphone:hama dinamic
operating sistem:win7 64 bit
audacity version:2.0.6 (downloaded file .exe)
…I can’t listen to your file at the moment, 'cause I’m at work.
microphone:hama dinamic
That’s not “computer mic”. That would explain the low-level and possibly the associated poor signal-to-noise ratio. Stage & Studio mics are low-impedance balanced (3-wire) whereas computer mics are high-impedance unbalanced (2-wire).
For good quality recording don’t use a “computer mic”, don’t use the mic-input on a laptop or consumer soundcard, and don’t use the mic built-into a laptop. Use a good studio/stage mic and an interface with the proper XLR mic input. Or, you can use a “studio style” USB mic (AKA “podcast mic”).
If the Hama mic is decent quality, the best/cheapest solution is probably something like the [u]Blue Icicle[/u] XLR to USB 'adapter".
There are higher-end multiple-input interfaces (and higher-end microphones) available from places that sell musical instruments and pro sound equipment.
this microphone has got a xlr imput.before that, I had another microphone without xlr input and worked well .
OK, I listened to the noise file… Yeah, that’s a nasty buzz. It’s hard to tell where it’s coming from. It sounds like power-line hum along with some other noises.
But in any case, the interface & connections from an XLR mic are just wrong for a computer’s mic input.
There is another (cheaper) solution besides a USB interface. You can use a [u]microphone transformer[/u] to match the impedance and convert the 3-wire balanced connection to an unbalanced 2-wire connection. But, you’d still be using the microphone input on your computer which is typically low-quality.
i tried to use another program.and the noise has disappeared.the voice is low,but the noise…puf!so…is it a problem of audacity softwer?i prefer to use audacity!
What happens if you amplify the voice in that recording? Does the noise reappear?
Audacity does not modify the input signal. It is conceivable that sample rate changes are making some of the noise if the other application really produces a noise-free recording.
Try changing the project rate bottom left of Audacity to 44100 Hz or 48000 Hz if it is not already set to that. Try changing the host in Audacity’s Device Toolbar.

the noise doesn’t reappear in the other program.the project rate is on 44100 hz.
about the power of the mic :could i solve with an external sound card ? What would you recommend with a decent quality and without spending too much? I would like to record a CD for my mother , I do not have to do anything professional, but I would get a decent result
I tried to change the option MME in WINDOWS DIRECT SOUND and I think the sound of the voice is better.what can you tell me about this option ?
a strange thing happened : the noise has disappeared…about the power ( as I wrote above ) What do you recommend ?
about the power of the mic :could i solve with an external sound card ?
Yes. You need an interface with an XLR connector (and a low-impedance mic connection).
The Blue Icicle I suggested above is essentially a special-purpose record-only***** “soundcard” with an XLR mic input.
[u]Musician’s Friend[/u] has a good selection of audio interfaces. Anybody doing “serious” home recording uses an XLR interface or a “studio style” USB mic such as the [u]Blue Yeti[/u]. …I’m not trying to push products made by Blue… I don’t actually own anything made by them.
With a $100 - $100 microphone and an XLR interface, you can get darn-near professional recordings (assuming you have a nearly-pro “performance” to record and a quiet “studio” with good acoustics.)
P.S.*
If you want to monitor yourself with headphones and with no latency (no delay) while recording, look for an interface with a headphone-output and zero-latency hardware-monitoring (where the monitor signal doesn’t go through the computer).
The Blue Icicle doesn’t have a headphone or speaker output of any kind. With that kind of interface, you’d have to monitor yourself through your regular soundcard and you’d get some delay.
so i need an interface with an XLR connector and with headphone and mic input?sorry if i am repetitive but i am inexperienced.can i find with reasonable prices ?
If I answer again, I’m going to be repetitive again… Re-read my posts and click a couple of the links.
ok,tomorrow I’m going in a musical instrument store.thank u
