![]() Some applications have automatic features that will scan an entire file for internal clicks and attempt to repair them. When creating loops, it should also be noted that if the end of the loop has a decreasing amplitude, the beginning of the loop should continue in the same direction or that can also create a click. Stereo files present an additional challenge because both channels need to be at the zero-point simultaneously. In some editors you can set the selection function to automatically jump to the nearest zero-point crossing or you can do it manually. This is the ideal place to trim a sound file because if you cut it anywhere else, the audio will be forced to jump abruptly to a different value when spliced to another another section, thereby creating an audible click. Clicks and Zero-Point Crossings: A zero-point crossing is the place where the amplitude of a sound crosses the zero or center line of a waveform. They allow ultimate control of every aspect of the sound down to the sample level, allowing you to tweak with ease and well beyond the limits of most DAWs.ġ. The use of a waveform editor is crucial in this process and part of my preproduction in developing content and material to be used in larger contexts.Īnyone that creates and uses samples (as individual files or in a sampler instrument) or audio loops can reap the benefits of a waveform editor. You could simply select the area and delete the content, or reduce the amplitude for a more subtle approach.Ī major part of my artistic practice as an experimental composer involves isolating fragments of field recordings or improvisations in my studio recorded with synths or guitar. ![]() It is often a good idea to remove background noise in multiple passes, using a more subtle approach each pass, as opposed to an aggressive one-time pass, which may introduce the notorious and hated gurgling effect.Īnother benefit of the spectral view is that short transient noises become immediately apparent and can often be easily eliminated like erasing an unwanted splotch in a graphics program like Photoshop. They are often used in conjunction with a DAW.įor example, if you preconfigure your Audio preferences in Logic to use a specific waveform editor, selecting a region and clicking will open the file in the waveform editor, where you can perform destructive editing and directly replace the file in the session. The true benefits of the waveform editor lie in their graphic interfaces and their ability to surgically isolate, tweak, repair and polish a single sound or sample. While some editors do have multitrack functionality, I prefer to record and mix in a DAW. In programs like Audition for example, clicking on a True Peak level in the amplitude statistics panel will move the cursor directly to the problem spot on the editing window. This allows you to instantly identify and locate problems with inter-sample peaks, RMS and perceived loudness levels, correlation and phase problems, clipped samples, etc. While you can edit audio files or regions in any standard DAW, dedicated waveform editors are optimized for this purpose.Īdobe Audition Amplitude Statistics panelĪ feature-rich editor will allow you instant access to amplitude, frequency and phase statistics on a specific file or a selected part a file. ![]() #Ocenaudio review pro#Difference Between a DAW and a Dedicated Waveform EditorĭAWs like Pro Tools and Logic Pro are intended for multitrack session projects. If you find yourself editing single sound files on a regular basis, finding the right editor will be time and money well spent. There are also freeware and shareware choices such as Audacity and Ocenaudio, low cost apps like WavePad and Loop Editor, and even browser-based applications such as Hya-Wave. ![]() While most DAWs are capable of waveform editing at some level, anyone that wants to get surgical about sound editing will need some sort of dedicated waveform editing application, such as Adobe Audition, Sound Forge Pro, SpectraLayers Pro and iZotope RX 6 to name a few. Knowing the basics of waveform editing is essential for sound designers, field recordists, composers and performers that use samplers or loop-based material, dialogue editors, and anyone that’s involved in audio editing in general. ![]()
