SoundSoap is the first professional–quality noise reduction solution that's also easy enough for average consumers to use. With just a few simple controls, anyone can remove clicks and crackles, unwanted hiss, room noise, rumble, electrical hum, clipping, low volume, and other noise problems from almost any digital media file — including digital video (DV), digital audio workstation tracks, analog cassette/tape recordings, vinyl LP recordings, and more. SoundSoap is a must-have for easily cleaning up audio before you share it.

Soundsoap 5 includes groundbreaking new features like automatic noise detection, a graphical learn noise mode, metering, MP3, FLAC, improved hum removal, additional media playback controls, and more:

  • Automatic noise detection* - SoundSoap analyzes media files automagically and will try to find the best location for learning noise. SoundSoap then automatically learns noise at this location rather than using a default, flat noise profile.
  • Set noise location* on the waveform display in the Media Window - move the vertical red indicator to learn noise at a new location in the media file.
  • Waveform display for video* - now you can toggle a view between video and the audio waveform display.
  • Improved hum removal - the hum removal algorithm has been greatly improved.
  • Enhanced media controls* - return to start, backward, and forward key commands.
  • FLAC and MP3 support*.
  • Audio metering.
  • Full Bypass* - the Power button on Media Window now bypasses all SoundSoap processing for true A/B comparing.
  • Reset* - reset all controls and the noise profile to their default settings.

* = features available using application but not available to plug-in version.

Amazing results are just a click away — SoundSoap's user interface is designed to be simple and focused, making it easy enough for anyone to use. A single click of the Learn Noise button solves most simple noise problems, and a few extra clicks offer powerful fine–tuning, for even better sounding audio. Simply drag in your video clips from iPhoto or another media application into the SoundSoap application. Or, use SoundSoap in ProTools, Garageband, Sonar, Logic X, Premiere CC, Final Cut Pro X, Digital Performer, EDISU, Sound Studio, Peak, Pro Tools, or any other application that supports the SoundSoap plug-in (Audio Unit/VST, 32 and 64-bit format, AAX 64-Native, RTAS 32-bit format (Mac) for ProTools 8/9/10).

Cleaning audio is with SoundSoap is simple - the Wash Window shows the sound "before" and "after" cleaning.

Share your spectacular results directly to Facebook, AirDrop, over email, and more.
SoundSoap removes clicks, crackles, unwanted hiss, room noise, rumble, electrical hum, clipping, low volume, and other noise problems.

SoundSoap's Loudness Maximizer boosts the volume of your audio tracks without introducing distortion. The Declipping feature automatically fixes distortion on audio that was recorded too loud, using an advanced digital signal processing algorithm to restore clipped audio signals. The Track feature automatically reduces the amount of noise reduction during louder sections of the audio material, effectively increasing the amount of noise reduction you can apply. It is like having your own audio mastering engineer riding the noise reduction controls. SoundSoap also saves WAVE and AIFF files in 24-bit format for pristine audio quality (Mac). SoundSoap includes a large parameter value display and a waveform display now shows the audio material when working with audio-only media sources.

Any way you choose to use it, SoundSoap's advanced audio restoration technology does the hard work for you, and gives crisp, pro–quality results in just seconds. SoundSoap's technology isn't the only amazing thing — the price is too.

SoundSoap-3 by Soundness is superb audio noise reduction software that comes in both application and plugin (VST, component, and RTS) form. Upon launching, I was immediately struck by a visually pleasing interface. The next thing I discovered was how straightforward, user-friendly, and intuitive it is to use this software. This is one of the rare audio editing tools that are easy to use, yet powerful. It does everything it claims to do, and it does it really well. There's plenty of control without any of the bloat that is often associated with editing software, i.e., you won't find a ton of unheard of features that make you scratch your head and ask,"What the?" SoundSoap-3 is easier, faster, and way more effective at removing noise than the filters and EQs that I've tried. It's a great product that is a pleasure to use. I no longer cringe when I discover audio noise on my tracks.


  • Slick, clean GUI.
  • 64-bit compatible.
  • Effective algorithms.
  • Also useful with video files.
  • Hiss and Buzz — SOAPED.
  • Hum and Rumble — SOAPED.
  • Clicks and Crackles — SOAPED.
  • Background noise and unwanted voices — SOAPED.


  • Next time I record I just might turn up the amps, turn on a fluorescent lights, and crank the A/C just so I can soap them clean before mixing.
  • Users can throw out the dirty bathwater and keep the baby.
  • My old sample library will soon be made clean.


I'm a clean freak, and nothing bothers me more than dirty audio tracks. SoundSoap is my mop; it's my broom; it's my sponge; it's my. .. you get the idea! Best of all is the price. It's a super value for what it does and how well it does it. If I only used it on a couple tracks I would feel compensated for my investment. If you are a well-paid pro, working in a top-notch studio, I'm sure there are more powerful options that do more; yet, for everyone else, this probably does what you need for a fraction of the cost and without the headaches. I highly recommend this software to any pros or hobbyist, who is working with recorded audio and needs fast and effective results. Tommy Zai gives SoundSoap-3 two squeaky clean thumbs up. Thank you, Soundness, for developing such a useful, rewarding, and satisfying audio noise reduction software.


Soundness just released a significant update to SoundSoap. Without hesitation I upgraded to the new version v4, and I have no regrets. The latest release adds some cool features. The Loudness Maximizer is sweet — the perceived auto signal is boosted without any added noise, distortion, or other goop. This is very nice. The Declipper is a feature that makes me wonder how I got along without it. I've had countless tracks along the way that suffered from a distorted spike or two. In the past, my options were limited. I either used SoundSoap to remove some of the unwanted stuff and then normalized the peak and lived with that rough segment of audio. Whatever algorithm they are using to declip is top notch (pun intended) and effortlessly corrects nasty spikes. The update/changes list includes several other improvements and fixes that I'm sure I will uncover as I soap up additional dirty tracks. Yet, the Loudness Maximizer and Declipper feature were enough to make me smile and increase my user review rating. Fanstastic! SoundSoap is evolving. I can't wait to see what v5 looks and sounds like!

Update Conclusion: SoundSoap v4 remains user-friendly and will continue to appeal to home studio musicians, and with the new features, seasoned professionals will find it hard to resist.


This latest release boasts some serious new features, most notably Automatic Noise Detection. Users are no longer required to manually scan for the best noise location to build a profile. This can now be accomplished automatically. The A.N.D. is used to find the noise and the users can visually adjust it. The algorithms are top-notch, and my experimentations have led to great results. I was a little apprehensive at first as I apparently have some audio control issues. I usually prefer diving in and doing the work myself, but after a few rounds I gained trust and let SoundSoap do the work for me.

MP3 support has been added, which is very sweet. I have a ton of low-fi audio files that I use for various projects. I no longer have to convert them into .AIF or .WAV for cleaning. I also dig the new metering. I tend to use my eyes when working with audio, and this makes it easier and more fun. The new and improved hum removal goes beyond an add-on feature. It's now a powerful element of the larger whole.

In the end, I went with SoundSoap+, which offers much more control for not much more money. I've heard great things about the Broadband Range control feature. I need to spend more time noodling with it. I also look forward to uncovering the coolness of the other bonus features found in the + version (Downward Expander, Enhanced Enhance, control over the threshold setting used in the Track control, etc.).

Comparisons: I have less experience with the other noise reducers on the market, but I did a great deal of research, demoing, noodling demo versions, and checking-out friends' copies before going with SoundSoap. I chose SoundSoap for the following reasons:

  • Great value.
  • Interface is simple, yet powerful.
  • Shallow learning curve. I like to work fast and furious without getting bogged down by what's under the hood.
  • This all began with the developer, BIAS. Their app called Peak was my favorite software of all time. The original SoundSoap was a bit of a cool add-on, but since being taken over by Soundness, it's become a serious force.

Why didn't I buy iZotope RX? Their Spectral Analysis remain a great feature — spectral "replace" function is very cool. Yet, I couldn't afford it, steep learning curve, stability concerns, and some features are more complicated and difficult to use, i.e., the denoiser.

Why didn't I buy Waves Z-Noise? More complicated and requires more fiddling to get results. Unable to scrub away enough noise. X-Click and X-Crackle are easier to use, but they are more specialized.

Why didn't I buy Sony's SpectraLayers? It's a very serious application, and I was not able to quickly dive in and get anywhere. Having a manual for this beast is a must.

Update Conclusion: SoundSoap v5 offers several excellent improvements. In my opinion it's well worth the initial purchase or an upgrade. There is still nothing comparable at this price. The floating soap bubbles on the transport section of the interface still make me smile each time I launch — fun stuff. Tommy Zai continues to highly recommend this upstanding audio app to anyone working with audio files, whether he/she be an amateur or professional.
