Reducing noise but keep speech - Soundforge or other?
I've been known to run folks' stuff through SoundSoap on my Mac. How many are
you talking about? wrote: I have some recordings of people speaking, which are obscured by a high degree of noise; the recordings being from aircraft, subway trains (the Tube), general outdoor/street noises. I need to keep the speech intact as much as possible, while reducing noise; said noise being generally much louder than the speech. Is this at all possible? Can an app like Soundforge do it, I see there is a Noise reduction option with SF? Are there other specialist (Windows) apps which might work, or any audio editing apps which are reputable for this application? thanks...... |

Beware of killing intelligibility even if your first impression is that a
given process helps audio quality. Losing low-energy consonants can definitely make dialog harder to understand. There seems to be an absolute plague of unintelligible dialog in current feature film mixing, and one suspect is the various dynamic noise reduction processes that are popular. I started to doubt my hearing, except that older films seem to sound just fine. This trend is a real mystery to me. In the good ol' days, dialog intelligibility was the #1 goal in motion picture and television sound. In article , says...

... AFAIK, Soundforge & the simalar Cooledit have functions to sample the noise & then subtract that from your programme - works best on continuous, cyclical noise like hum or airconditioning units etc - That's true. If you're lucky and can find a good section of voice you can also approach it from the reverse angle. Sample the voice and set the plugin to "keep the noise". This can sometimes work in a pinch when you can't get at it from the other end. From that standpoint the voice may be more "continuous" than the random noise. |

I started to doubt my hearing, except that older films seem to sound just fine. -----------------------------snip---------------------------- There's a trend in modern feature film sound recording today to try to use the actual production sound dialog as much as possible. I think in the old days, at least half of the dialog would be looped; in action films (like STAR WARS in the 1970s), probably 3/4 of the dialog would be looped, maybe more. But it's a lot different today. Part of it is a creative trend, where the directors know that the performance from a line looped in an ADR studio will be markedly different than what was done on location. You can make a good argument that great actors can actually improve performances this way, but I suspect that actors are losing this ability as new generations come and go. And it's hard to argue with the fact that a looped line never sounds quite the same as one done on location, no matter how much EQ, reverb, or processing is done to the sound. And another part is that the equipment has improved to the point where small microphones, digital wireless transmitters, and digital recorders have made it much easier to get good dialog quality on location. Multi-track recording makes it possible to use a plethora of wireless mikes, shotguns, and hidden mikes, even within the same scene, so that no actor is ever out of range. But the real problem (IMHO) is speed and lack of post-production time. Movies are being rushed through so quickly, there often isn't time to bring an actor in and re-record the dialog. So the poor mixers have to basically just make do with what they have, even if that means subjecting the location sound to massive amounts of digital processing to remove generator noise, clothing rustling, wind noise, etc. Lastly, there are problems where some inexperienced directors ignore warnings from experienced mixers and demand excessive levels, sometimes at the expense of dialog intelligibility. There's no easy answer to this, but well-recorded movies do still exist, and not all movies sound bad, even today. --MFW |

Reducing noise but keep speech - Soundforge or other?
I have some recordings of people speaking, which are obscured by a high degree of noise; the recordings being from aircraft, subway trains (the Tube), general outdoor/street noises. I need to keep the speech intact as much as possible, while reducing noise; said noise being generally much louder than the speech. Is this at all possible? Can an app like Soundforge do it, I see there is a Noise reduction option with SF? Are there other specialist (Windows) apps which might work, or any audio editing apps which are reputable for this application? thanks...... If the noise is louder than the speech, you are pretty much stuck unless the noise is outside of the main speech band of 300-3kHz. Noise reduction systems either work on playing with phase relationslips oe frequency controlled expansion.. If the noise is louder, it pulls the speech aswell as the noise. Richard H.

Sounds like you need something along the lines of forensics. You might give
a look at Diamond Cut software, DCLive or DCart, which has some forensics applications. -- Joe Salerno Video Works! Is it working for you?
