how to boost audio level of camera's mic

->> I use my camera's microphone (1dmkIIN) for recording names, details, etc. In a noisy environment, I real have trouble hearing those recordings later when I play on laptop using photo mechanic.
Computer's speakers volume is maxed. My other laptop has same problem. I put my head down to the speaker, so my ear is touching the thing. It's ridiculous and brings weird stares in Starbucks.
Is there some kind of freeware or something out there that will boost levels on my computer? Even with headphones, its tough to hear sometimes. |

->> Robert,
Make a copy of the wave file that is attached to the image file. Open the copy in an audio editing software that allows you to do waveform edits. A good free program would be audacity.
Import the audio and use the gain tool to boost the audio. You should hear things better now.

->> How about trying a pair of earbuds? The coffeshop crowd will just presume it's i-tunes and go on about their business.
Also - somewhere around here I've got a line in / line out to USB converter. It has a mini socket for phones, but I'm not sure of it's go any gain. That could also be an answer if you need to listen to notes as you edit.

->> Also, if you are listening with earphones, you can try an in-line signal booster like this one from Radio Shack:

which is almost certainly the same product as the original Boostaroo:

->> Robert,
I hate to ask the obvious, but when you're recording your voice notes, are you speaking closely into the back of the camera? In loud places (like basketball games), my mouth is almost touching the mic on the back of the camera (which on my 1DMKII, is located near the main dial on the back of the camera), and I'm projecting my voice at the same time.
I listen to voice notes off two 1DMKII bodies on my Macbook Pro, as well as my G5 Tower all the time and I have to turn the computer volume down while listening... |

->> I'm with Guy and his low tech answer. I've often cupped my hand around the mic and spoke into my hand. Looks even more bizarre than just talking to your camera but it's more than loud and clear enough to hear out of powerbook speakers. I just saved you $25 on the cost of the Radio Shack amp and time in extracting the wav file in an audio editing program. The bill is in the mail....

->> At the Ohio high school state swim meet this past weekend, I was constantly recording voice notes on photos to keep track of swimmers and races, etc. An older gentleman working at the meet saw me talking to my camera and asked if I was alright in the head. I just told him that if I talk nicely to it, it will give me better pictures. "Good camera, that's a good camera."
I have found though, that the closer your mouth is to the camera, the less ambient noise it records. Cupping your hand over your mouth, like Michael said, is a good idea. |
