How low a noise floor do microphones have to have? A microphone with 16dBA noise floor might be OK if you are using an acoustic amplifier like a parabolic reflector, or recording louder sounds of thunderstorms, creeks, or closeup subjects. When you are recording low levels, microphone self noise starts to become a noticeable issue. Field recording generally involves recording low level sound. So, microphone selection is key to producing a low noise result. The noise from a microphone will always be higher than a good recorder's noise floor. Many low cost, hand held recorders can offer excellent results, even with EINs greater than -126dBA, when paired with products from Wildtronics that have the built-in low noise preamplifiers. The good news is that today there are many very good recorders available at lower prices than ever. The absolute best A/D converters can achieve 140dBA SNR, but the overall SNR will be lower. The specification of interest is the overall SNR (Signal to Noise Ratio). Almost all ADC's are now 24bit depth and some newer recorders are 32bit depth, which is great but a little misleading. The A/D processes the analog signal and converts it to a digital format. The next thing to look for is the A/D specification. Generally, anything less than -126dBA is good (a larger negative number). You could do an internet search to see if others have measured the recorder of interest. This may be a challenge, as many manufacturers do not like listing the spec.
A key number to look for in recorders is the EIN (Equivalent Input Noise) specification. Processing very noisy recordings will never result in the best sounding final output.

With all the technology available today, there is no excuse to hear microphone hiss in any professional recording.įirst, you really need low noise equipment to start with. Processing and reducing noise should be part of the work flow of editing sounds. From my experience with recording natural soundscapes for over 20 years, I would like to share my technique for eliminating background equipment noise. People have asked us over the years what is the best technique for reducing background noise from audio recordings. On this day.Technique for Eliminating Equipment Noise Check out Wes' video tutorial library, "Playing with Media." Information about more ways to learn with Dr.

Technorati Tags: audacity, software, podcasting, noise, remove, removal, wavpad If you’re interested in the techniques I used to normalize the audio file and compress it, I created a screencast of that process a couple of weeks ago you can check out. I’d love to hear about other free/affordable noise removal audio editing programs besides WavPad, so please share a link as a comment if you’ve got suggestions. It doesn’t appear Audition is available for standalone purchase, and I don’t really want to pay hundreds of dollars (or even thousands) for an Adobe Creative Suite bundle.

Do you know of or use a better free (or inexpensive) software option for removing background noise? I tried Audacity‘s noise removal effect but didn’t get good results, WavPad worked better.Īt MacWorld in 2007 I saw a vendor floor demonstration of Adobe Audition‘s background noise removal power and was totally blown away. I am not entirely pleased with the results, but it is better than the “noisy” original.

I lastly uploaded it to my “ Fuel for Educational Change Agents” podcast channel which is running free/open source Podcast Generator software. I saved the edited file in WAV format, normalized it using free Levellator software, and then converted it to a 32 kbps mp3 file using Switch software. Then I chose “Apply Spectral Subtraction” from the EFFECTS – NOISE REDUCTION menus. After opening the raw mp3 audio file in WavePad I selected a small portion of the recording (about 2 seconds) in which no one talked and ONLY the fan noise was audible.
This evening I used the free/home version of WavePad software to “Apply Spectral Subtraction.” This was a two part process. Unfortunately there was a loud heater fan running in the classroom where Amy shared the presentation, which is pretty distracting in the “raw” recording.
I took notes and shared links during her presentation, and also recorded the presentation with permission using my iPhone and the free iOS app/service Cinch. Yesterday I heard a fantastic presentation in Yarmouth, Maine, by teacher Amy Sanders about her Arab Spring Project.
