This is a great article on the history of reverb and echo, definitely worth a read if you get a chance.

The Mix was an intense process. Without many instruments we had to create a full sound. With the help of Logic 9, I think it went pretty well.

All songs were recorded in the one session and each instrument had the same track for each song, so these settings were applied to all songs, then split off and minor tweaks were made (most of which probably won’t be mentioned because they’re not really very interesting.) Sam wanted his EP sound to be really consistent so we decided doing it like this would be a fun, challenging and interesting approach.

I started mixing the first song, which was probably the thinnest of the lot with nothing but guitars and vox. It’s quite an intense and raw song and I wanted the EP to start strong. I started with the guitars and did the usual pan each mic to either side, high pass and low pass EQ to keep out sounds not in the frequency range, some low mid cuts and a slight high mid boost to eliminate any masking, compressor and a noise gate. This got it sounding pretty good, but after mixing everything else the guitar just seemed to not… sit right, it was just a little overpowering in the high mids, so I decided to do something I tried in a different mix. I put a stereo spreader on both guitar mic tracks and spread the upper mids a little, order 11 for one and 12 for the other so the same frequencies weren’t being spread on either side. Being already panned to one side, this pushed some of those frequencies just a little closer to the middle, widening it at the loss of some of its power, perfect!

 

On the left we have the left guitar mic and its plugins, on the right, the right!

 

The vocals were a lot more simple, just a matter of EQ, compression, noise gate, and a tinyyyyyyy little bit of delay.

 

Now the lead guitar was interesting, for the electric lead solos we had 2 mics, one dead on and one to the side, so I panned them to show this. This sat the guitar slightly to one side but still gave a nice full sound, almost like if a band were playing and the guitarist had come up to do a solo and was standing just to the right of the singer.

Here you can see the centered mic on the left and the panned right mic on the right, as well as the EQ, compression, noise gate and delay decisions I made.

Next was the acoustic guitar solos, there wasn’t really anything special done here, it was recorded with a single mic so I opted against any crazy stereo imaging, quite a decent amount of EQ and delay, and more compression than I normally try to use, then a good ol noise gate.

 

The only other major instrument recorded was the double bass, once again a pretty simple process, decided to go for some more creative EQ to try and keep the clarity of the double bass whilst removing resonances and fixing some masking problems.

 

There were some other instruments used, including an egg shaker, a MIDI glockenspiel, a MIDI kick drum and some whistling, but I opted against doing those ones as they were very simple processes, but if anyone is interested let me know and I’ll show you how I did them, or help as best I can with mixing those instruments.

The final part of the mix was the reverb, this was done by setting up an auxiliary channel strip and putting the space designer reverb on it, then bussing all tracks to it. I don’t know very much about designing reverbs, in reality or in plugins, but I found the preset my ears agreed with most was the small booth reverb. It just sounded right and fitted the style perfectly.

I also used a concert hall reverb on the vocal echoes in the first song, ‘Heaven’.

If anyone has any advice for my mixing process for future mixes, please don’t hesitate to send it my way!

Also, please look up Sam Luff on facebook! or soon iTunes! He will be extremely grateful and is very much worth your time!

A synth is created through tone generation, manipulation, and amplification.

Generation:

A basic synth will often have a single oscillator (the generator) with the ability to generate some kind of sound wave, the most common being the square, saw, triangle and sine waves.

To start building a synth sound, first select your wave. The square wave has quite a ‘woody’ sort of sound, and is often good for bass synths, the saw wave is quite sharp and a common lead synth wave, the triangle wave sounds similar to the square wave but a bit more dull and harmonically weaker and the sine wave is very pure and lifeless. This is because the shape of the other waves creates harmonics, and if you were to filter out the frequencies around the note you were playing you would end up with something that sounds like a sine wave anyway.

These waves are often not the only choices, many synths offer you the choice of combining two waves, and some synths offer you noise waves, or even the ability to create your own wave shape.

So depending on your synth, these are your choices… for one oscillator. Very often synths will have multiple oscillators, giving you the ability to layer sounds on top of each other, and blend the volumes for an even or one sided combination, as well as a pitch control (often used to put an oscillator up or down and octave, but sometimes used for different intervals, be careful with using intervals other than an octave, it might sound cool at first but it could create problems in the harmonic progression of your song.) Individual detune controls are often available to add some crunch by putting oscillators slightly out of tune with each other.

Many synths also allow you to choose how many unison voices the synth has, which essentially means the synth adds multiple copies of itself onto itself, this is a great way to create a really huge sound, but don’t get carried away or you won’t leave any space in your mix for anything else!

If you’re just starting out I suggest you just use one or two oscillators, and stick with basic wave shapes, one of my favourite sounds is 2-3 oscillators all set to a basic saw wave. Which sounds kind of boring, but here’s where it gets more interesting.

Manipulation:

The first manipulator is the ADSR envelope (an envelope is where the signal passes through to be manipulated, feel free to call it the manipulator thing.) This stands for Attack, Decay, Sustain, Release.

The attack is how long it takes for the synth to go from no volume to peak volume

The decay is how long it takes to go from peak volume to sustain volume

The sustain is the volume from the end of the decay period to until the note you’re playing is released

And the release is the time taken for the sound to reach silence after the note is released

This is best shown using this graph:

Slow attack and release times are most common in pads to allow the chord to swell up and fade away.

Decay and release are only experimented with excessively for more unusual kinds of sounds.

The next manipulators are the filter and resonance:

The filter is used to roll of frequencies above a certain point, sometimes you are given control of how fast they roll off as well. This is often used to filter out unwanted harmonics or if the high frequencies are masking another sound in the mix and you feel you don’t need them. Another common use for it is to have the filter set low and automate it to open up gradually, allowing the synth to grow and fill out the audio spectrum. If you don’t know how to automate, leave a comment and I’ll do a post on it as I won’t be going into that in this post.

The resonance is a control to create a resonance at a certain frequency, making it more prominent in the sound. This is often used to create a bigger bass sound or to emphasise some interesting harmonics in lead sounds.

Other manipulators are –

The LFO: This stands for ‘Low Frequency Oscillator,’ but it doesn’t generate sound, however it is still a waveform, this waveform is just used to control other aspects of the synth. A common use is to have it control the volume on a bass synth so that the volume fluctuates at the rate the wave is set to, the wave is then often synced to the song tempo, and there we have… WUB WUB!

Other uses are to control things like the filter, the pitch, the resonance or anything really, and you can get some really insane sounds.

Effects: These can be anything from chorus, flange, delay, reverb, or many other things, but I won’t be going into these in this post either.

Unison Detune: This is often a single knob to control the detune for all the voices in the synth that aren’t given actual oscillators.

I’m sure there are lots of synths with manipulators I haven’t mentioned, but these are what I’ve found to be most common, but if I’ve forgotten an important one, let me know!

Finally, the amplifier:

This isn’t really something you need to think about unless you’re using a hardware synth that requires an amp to make sound, in which case you will just have to buy an amp and get familiar with it, because all amps are very different. Software synths are amplified by your DAW or your computer (if its a standalone synth) and played through your speakers.

There is also another kind of synthesis called FM or ‘Frequency Modulation’ synthesis, but I will save that for another post as it gets quite complicated.

Thanks for reading, hope you found this helpful, if theres anything you’d like me to do a post on, let me know!

Everybody knows that the most important part of working with sound is having good ears, these are my personal favourites for ear training:

Apps:

Quiztones- this app lets you choose to either train your tone recognition, or your ability to hear EQ changes in various instruments or your own music, and if you upgrade to pro you get gain level comparison and EQ expert quizes as well!

http://quiztones.net/

EQ Trainer- EQ trainer is only for training fundamental frequencies recognition, however it is has much more variation in difficulty and also is designed to help you improve your speed at recognising them.

http://itunes.apple.com/au/app/eq-trainer/id458969341?mt=8

Remember: apps are good to keep your practice up, but they only go so far in difficulty, for really serious ear training you will probably need to try one of these…

Audio Books/Listening CDs:

Golden Ears- Golden Ears is a very intense ear training course for anyone really serious about sound engineering, it trains your ears on frequencies, effects and processing, decays and delays, and then returns to do more advanced work on frequencies. This is an incredible course, I very highly recommend it. The other products on the Molton Laboratories website are worth mentioning too. These include the ‘Playback Platinum Series,’  ‘Total Recording’ by David Moulton, Recording Magazine, and I could go on. Golden Ears (and Total Recording) were created by KIQ productions.

Critical Listening Skills for Audio Professionals- This course is great because it just asks you to sit and listen to the different sounds, rather than write down guesses for listening tests, which isn’t a bad thing, however, I find sometimes I would rather just listen and learn than be constantly testing myself.

Other:

www.trainyourears.com Train Your Ears EQ Edition- this is another good ear training resource, however I would still recommend one of the CD courses.
