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.
#ADOBE AUDITION NOISE REDUCTION OR VOLUME LEVELER PROFESSIONAL#
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. Technique for Eliminating Equipment Noise
