How To Produce Music In An Easier Way? Tips On Using Samples In Audio Editor 2021

Whether you are writing your entire compositions using samples, or whether you just need to slice a half second clip to transpose in your sampler, you need suitable tools for the job. In this article we will discuss sample manipulation using audio editors wand what exactly they do. What we will describe can be done by most of the major audio editors. These include Steinberg WaveLab, SoundForge, Adobe Audition and a few more which can often come in software bundles

Cut And Slice The Samples

Cutting, copying, pasting audio files is probably one of the most common functions of your audio Editor. In sequencers you usually slice audio using the scissor tools, with audio editors however this is using done by highlighting the sample. One this to keep in mind is the importance of slicing in units. You want to be able to use your slices rhythmically within your track, and by not accurately slicing your audio files they can often sound choppy. This create an uneven fluid to your samples and creates slight breaks in rhythm within your tracks. Be careful to make sure that the measure code in your audio editor is at the correct time format. The meassure code can be assigned in your preferences and can range from samples, minutes to even beats.

One of the first things you will want to do is see if your audio editor has any zero-crossing points options. What this means is that the horizontal line where the waveform crosses is at zero amplitude and therefore it can blend into other samples or loop itself without hearing glitches or clips. This is a major part of editing good samples. Check your manual of your audio editor and see whether your editor has this functions, all this big ones do.

Although important slicing at zero crossing isn’t always enough. If two samples are being blended and have contrasting timbres glitches can often be heard. Take advantage of your audio editors loop functions which can often help resolve the discrepancy in timbre. SoundForge’s Loop Tuner and Wavelab’s Cross fade Lopper both match the end of the loop against its start so you can see and hear exactly how the two areas blend. Then it becomes easy to adjust the looping start and end points. They also entail a crossfade looper which gentily blends the two samples or loops. There is also a Loop Tone Equalizer in Wavelab which actually adjusts the timbre and EQ Levels

Stretching Your Samples The Way You Want It

In the past if you wanted to speed up your audio clip you needed to alter the pitch in order to change the duration of a sample (think turntable). With new digital editing samples can be stretched or shrunk using your audio editor in order to give the sample the size and length you want. Different editors vary in function but Time Stretching as its called can usually be done in accordance with tempo, percentage, or desired sample duration. One must be careful though by stretching your sample too much or too little can often cause unnatural sounds which will not sound good if your intended purpose is realism. That being said there is ample opportunity to stretch samples and make them sound in way that the original sound designer never interned.

The Mighty Pitch Shift

Although the little sister to Time Stretching. The Pitch in no longer attached at the hip. One of the most common uses for pitch shifting is actually usually referred to as pitch correction. In order to keep your tracks in key, extensive pitch correction sometime might have to be done. Although this is easier to accomplish when dealing with certain harmonics than others. A vocal for instance is very difficult to pitch shift without a proper dedication unit such as Antares Auto Tune. Like time stretching though when shifting rhythmic chords or drum loops be careful not to deviate too far from the original pitch. The results can often be not so desirable. Some editors will include functions to preserve formants, which are a collection of harmonics that occur naturally in many sounds. An example of fomants which can also be found in bells and reed instruments but especially in the human voice. When shifting this natural feel is lost and the famous chip monk sound is heard.

The Pitch Bend

Another really nice function is Pitch bending. It’s not present in all audio editors, although it is in Wave Lab, SoundForge and Adobe Audition, this enables you to change the pitch of the sample over a time period. So you could for instance increase or decrease the pitch of a sample through out the sample. This includes using a a envelope curve so you can draw in the exact pitch. Although it may not be the most obvious tools, but subtle pitch changes can often be very advantageous in creating effects. Or on a more global scale this can be used to give the effect like when slowing down your records or pressing stop on your turntable platter.

Mono To Stereo, Or Stereo To Mono?

This is a pretty simple function and is pretty straight forward, but there are some pretty cool things that could even be done with this. An example would be the famous karaoke scenario where one can somewhat remove a vocal from a track. For instance most editors will actually let you determine how much of each channel you want to take form your stereo file. In most cases you will want to split it 50/50, but lets say you split 100% of the right channel on one mix and 100% of the left channel on the other mix. After converting these two files you can now put them back into a stereo track and they should phase each other and the vocal will be removed. Although this technique does work, it can be very unsuccessful depending on the nature of the audio sample.

Converting a mono to stereo track is just as easy, but if you do this your stereo track will end up sounding exactly like your mono track. So in editors like WaveLab and SoundForge there are special functions which can enhance the stereo field. Try Playing around and you will be surprised how effective these affects can be.

The Good Old Reverse

We have been hearing the reverse ever since the days of the Beatle(Strawberry Fields Forever?) but there still some great uses for the reverse. Lets Bring it up to date. The Reverse Can play a role in reversing atmospheres to create different variations or reversing vocal samples to make a some crazy effects. In dance music the reverse cymbal is still used in many tracks to signal the beginning of a new verse, chorus or breakdown.

We can give the reverse a twist by reversing applying effects and then reversing again. What this will do is give us a reverse effect that leads up to the main sound that created it. Try it out….. pretty crazy stuff. Heavy reverb always works pretty well gives the sample a slight backwards effect, but then the sound is heard correctly and it kind of sounds like its coming from a tunnel, but you really actually don’t know. CRAZY

Sample Conversion

Sample conversion is often necessary to convert samples rates and formats for instance if your friend gave you a set of samples he has been working on that are in 24-bit format in order to put them into your project which is being done at 16-bit you will have to use your audio editor to downsize the file in order to properly play it. This is more of a case by case example, but the point being audio editors can be extremly helpful in convering all different audio files to the form in which you need them.

In Conclusion

The modern day audio editor has become an integral part of the modern studio. Get to know your editor it will make your job editing 100 times easier. As mentioned earlier some editors will do some functions, but it is only the top of the line editors that can do them all. See what you need, you might not have to or want to break the bank if all you need is simple cut and paste editing.
