3 Free Exciting Sound Effects Generators

Sound effects generators are software programs that lets you create old school electronic sounds and effects – plop, thud, splat and boom - to use in games, videos and other projects. While free to use sound clips are abundant on the web, if you want your project to be unique you would create your own sounds. And if you are particularly weak with keyboards (the instrument), take a look at these synthetic sound effects generators.

sfxr

sfxr is a pioneering little program created with the purpose of providing a simple means to get basic sound effects into a game for those people who work hard to get their entries done within a deadline and doesn’t have time to spend looking for suitable ways of doing this.

By hitting just a few buttons in this application you can get some largely randomized effects. Basic usage involves hitting the randomize button or any of the other buttons on the left if you need a specific standard sound like explosion, jump, shoot etc. Listen to the generated sound and if you decide you like it, then export it to a .WAV file and you are done. And if you want to get your hands dirty, there are dozens of parameters that you can tweak manually to fine tune the sound. Sometimes even a small change produces unexpected results. Just keep trying and trying and trying.

Bfxr

Bfxr is a remake of sfxr with many more exciting features. It can be run inside the browser or as standalone tool downloaded to your computer. Bfxr contains all the button you will find in sfxr and some new things as well:

  • 5 new waveforms : triangle, breaker, tan, whistle, and pink noise.
  • 3 new filters : compression, harmonics, and bitcrusher.
  • Ability to lock parameters during mutation/randomization.
  • Expanded pitch-jumping abilities - good for arpeggiation effects.
  • Waveform visualisation
  • Mixer where you can mix two or more sound to produce new sound effects.
  • Keeps a history of sounds and mixes generated in persistent lists.
  • Can reverse synths

LabChirp

This is another gem of an app. Using only some basic parameters such as frequency, waveform, frequency modulation, volume modulation and envelope, LabChirp can produce an infinite number of varying sound effects. You can even graphically draw the envelope of the waveform which is real handy when you want to produce effects of varying tones and magnitudes like a crescendo. LabChirp also supports up to 8 audio channels.

There is also a randomizer for automatic sound generation. There are different presets to generate sound effects for in-game events like footsteps, jump, ouch, explosions and so on. Each click on the Randomize button produces a new sound.

Once you have produced a satisfactory sound use the File > Save As menu to export the sound as a WAV file. You won’t find the .WAV extension for selection in the Save as dialog box, but don’t worry, LabChirp actually saves the file as WAV even though it says LabChirp's own LCH format.

  1. Wow! Very nice article. I've been looking for some good sound generators for a looooooong time. Thanks for providing a rundown of three good ones!

How to Record CPU and Memory Usage Over Time in Windows?

Whenever the computer is lagging or some application is taking too long to respond, we usually fire up task manager and look under the Performance tab or under Processes to check on processor utilization or the amount of free memory available. The task manager is ideal for real-time analysis of CPU and memory utilization. It even displays a short history of CPU utilization in the form of a graph. You get a small time-window, about 30 seconds or so, depending on how large the viewing area is.

How to Schedule Changes to Your Facebook Page Cover Photo

Facebook’s current layout, the so called Timeline, features a prominent, large cover photo that some people are using in a lot of different creative ways. Timeline is also available for Facebook Pages that people can use to promote their website or business or event. Although you can change the cover photo as often as you like, it’s meant to be static – something which you design and leave it for at least a few weeks or months like a redesigned website. However, there are times when you may want to change the cover photo frequently and periodically to match event dates or some special promotion that you are running or plan to run. So, here is how you can do that.

Diagram 101: Different Types of Diagrams and When To Use Them

Diagrams are a great way to visualize information and convey meaning. The problem is that there’s too many different types of diagrams, so it can be hard to know which ones you should use in any given situation. To help you out, we’ve created this diagram that lays out the 7 most common types of diagrams and when they’re best used:
