Task 2: Auditory Imaging


Lecture

Week 6 / Multitrack editing 

To make it easier to work and organise the sounds in the multitrack session, make sure to name each track accordingly.

Track layering and effects
When you want to join duplicate sounds, try to overlap them to make the transition a lot more smoother. To group multiple tracks together in order to apply effects on those specific tracks, go to multitrack > add audio bus track stereo. After that, parent the bus track to the other tracks in the sidebar panel. Bus track in general is called as "sub-mixers".

The effects rack work in reverse of how layers work in Photoshop. The effect at the bottom takes effect last. One effect that people use to create some final touches is the mastering tool. Exciter setting in the mastering tool makes the sound crispier, but don't use too much. The effect parameters in the final mixer shouldn't be adjusted too much, if you find yourself increasing or decreasing the parameters a lot, then the effects should've been done individually in the multitrack.   

Volume level
For TV productions, the master volume level should be at -12 to -8. Input boost is only used when needed. Make sure that the volume level in the master mix and in each of the individual tracks do not have clipping.. 


Tasks

Task 2: Auditory Imaging
For this task, we are required to pick one from the 6 given scenarios and come up with a storyline based on the scenario. The storyline has to be descriptive as it will be used as the base to create the soundscape for it. If none of the 6 given scenarios are to our liking, we can propose our own scenario. 

The 6 given scenarios are:
1. Wildlife + Background
2. Everyday Home Life + Background
3. Cities + Transport + Exterior Atmosphere
4. Industry and Electronic sounds + Background
5. Weather + Background
6. Market + Rural atmosphere + Background

Storyline

Fig 1.1 Written storyline based on weather scenario

After thinking about the possibilities of the given scenarios, I chose the weather scenario as I had a story idea in mind when we were briefed about the project. I wrote the storyline with the idea of a person late for work and when she's rushing to her office, she encounters a rapidly changing weather. I wanted the weather to start of with a heavy rain, then changed to a sunny atmosphere, and finally a strong, very windy situation. After I'm done writing the story, I highlighted the foreground sounds in yellow while the background sounds in cyan so that it's easier for me to imagine the soundscape and search for suitable sound effects. 

Audio layering and editing sound effects

Fig 2.1 Audio layers in Adobe Audition multitrack

I first started with layering all the audio tracks and editing them as I go. I started with background tracks at the top and layer the remaining audio according to time of appearance, length of audio track and track effects. For audio tracks that adds to the ambience, most of them are layered in Track 3 or Track 4, while audio tracks that needs specific track equalizer effects, I put them together in the same track and adjust the other tracks accordingly. Footsteps audios mostly are arranged in Track 6 and below. I mainly used track automation to control the volume, panning and equalizer effects, and used clip automations on clips that I plan to possibly move later on. Though, no keyframes were used in clip automation, only the whole audio track volume and panning were changed.

Equalizer and pitch shifter are the most used effects to alter specific audio tracks. Some audio tracks I used them on are to muffle sound of rain dripping on umbrella and a telephone ringing sound to make them sound further away. As for pitch shifter, one of the tracks I used it on is to pitch down and pitch up a footsteps sound effect to create more variety when they're layered on one another.

Further development of audio editing mix

After receiving feedbacks from Mr. Razif, I went to alter the pitch of some sound effects and further work on the volume automation. I also changed some sound effects from the first draft as I found that altering some of the previous sound effects would make the sound have a lot more artifacts. Some of the audio clips are cut at different portion and rearranged again to make the sound effect better, such as the paper rustling sound when the person is heard grabbing papers. I also adjusted the crossfading in the overlayed audio clips more to get a smoother transition. Other than that, the tracks are also rearranged and named for better organization. Since I didn't want my multitrack to have too many tracks which would make it hard to see where it's layered, I didn't separate the audio tracks by scene.

I also created multiple bus tracks so that I can apply different reverb effects on different sets of tracks. Bus A has a more echoey reverb, which is used for background sounds and some environment sound like thunder and rain. Bus B and the Master mix has lesser reverb, much like in a furnished living room, with the Master mix having slightly less reverb than Bus B. Both of them are used for objects and actions that is happening close to the person or is done by the person. Bus C has less reverb than Bus A but a lot more than Bus B, it is made for simulating the reverb in a toilet, but it is also used for when objects and actions are sounding further away from the person. In each of these bus tracks and Master track, I used automation to control the amount of the reverb at certain point of time using the rack mix automation, as shown in Fig 3.1. I also used the rack power automation to turn the effect on or off where suitable.

Further development of audio mix and reorganising of multitrack

Fig 4.1 Reogranised multitrack window

After receiving feedbacks from Mr. Razif, I reorganised my tracks by separating each audio in its own track. Though, audio that are similar to each other, such as different footsteps sounds and different door opening sounds, I put them in the same track so that there isn't too much tracks in the multitrack which will make it messy to see, and the audios use the same reverb settings too. I arranged the background ambience audios at the top rows, which are colour coded in dark green and purple, and the rest are arranged according to scene appearance. Audios that are colour coded in the same colours means they belong to the same scene, or type of audio.

Fig 4.3 Creating the bus sound in another multitrack

I removed the fade outs for the heavy rain sounds so that it would end more abruptly and wouldn't sound like a running faucet. Though, I moved the main heavy rain sound (the one highlighted in Fig 4.2) to end a bit earlier than the heavy rain under roof sound, so that it won't end too abruptly. For the bus sound, to make the main project multitrack more organised, I edited and layered the bus audio in another multitrack session. I added a bus door opening and closing sound, and an engine idling sound over the original bus audio to make the action of its door opening and closing more prominent.

I also removed the track automation for EQ band 3 gain because there was a problem with exporting that Adobe Audition can't export the EQ track automation for it correctly, so I had to remove it. Other than these edits, I also tweaked the volume and panning for some sounds to make them more clearer, and added fade in and fade out where necessary to make the transition smoother. I then exported the audio track in WAV file format at 48000Hz, 16 bit.

Feedbacks

Week 6
Sounds happening in the bathroom would need some reverb. The ambient sound when the person left the room and is going down to the living room, it should be different to differentiate from the aircon room sound. Maybe pitch it down or high up. The sound of the bus coming and stopping would need to be louder, and the bird would need to be softer than the bus. Maybe slowly fade down the volume of the bird sound as the bus comes in. Increase the volume of the bus door opening and closing. For the wind sound, maybe try to find sound of wind blowing at a mic to simulate the sound you hear in your ears when the wind is blowing directly at you. The sound of the person sitting down in the office chair would need to be louder. Overall the composition is not bad, there are a lot of things happening, just continue refining it with effects and watch out for the volume. 

Week 7 
Don't put fade out for the rain since it makes it sound like running water from a faucet, just cut directly. When the bus comes in and stops, add a slight fade in of engine idling sound. The sound of the bus door needs to be exaggerated more, you can try to make it louder, but it's probably best to find a different sound for the door. The current audio has the sound of the bus door swinging and hydraulics, but the sound of the door opening and closing needs to be more aggressive. Fix the huge reverb when he's picking up the paper in the wind. Overall is quite ok, nothing major to adjust, just that certain sounds needs to make it more established 


Reflection

This project was enjoyable for me to do as I got to learn and be more familiar with the functions and settings in Adobe Audition and how to work more efficiently in it. Though it took some time to get used to in organising the multitrack by different audio clips each since I got used to putting different audios together in the same track and only separate them for layering purposes, and using automation to adjust the effects at each section. Organising the tracks following individual audio does make it hard to see the whole layering process for me, but it makes applying effects in bus tracks easier as I won't need that much automation in the bus track to adjust the strength of the effect. Other than that, I also ran into some problems where I can't get the exported audio to sound like what was heard in Audition, and it was challenging to get the sound of people passing by in the rain to sound right. But I'm relieved that I managed to fix them with some work-arounds, though not the ideal ones. 

All in all, it was interesting and fun to try and make a sound scape without the visual of a video or a picture like in Exercise 4. Although there are parts that can be improved more in this project, Exercise 4 definitely helped in preparing me for this project and I'll continue to get more familiar with Adobe Audition in the next projects.
