Hollywood Bowl – Behind the Scenes

UPDATE April 23
At the request of people associated with The Bowl, I was kindly asked to remove the pictures that were posted here. I removed them as soon as I was made aware of the situation out of respect to the venue and all of the professionals who work there.

Thank you.

Rob Bridgett on Sound for Pre-School Games

Veteran game audio director Rob Bridget inspired me with his post-mortem on Zorbit’s Math Adventure for iOS and Android. These were my eight take aways…

1. Even among the few quality developers making compelling experiences for young ones, there are significant opportunities to improve the quality of the audio. More importantly, “the overall integration of sound and design seemed like huge missed opportunities in this genre.” Audio should be integral — not an afterthought — because sound plays a key role for a younger audience, especially dialog for pre-readers.

2. Rob suggests we owe pre-schoolers an especially safe loudness landscape in mobile games so as not to damage their hearing. From early concepting through audio implementation, sonic loudness was carefully managed. They even implemented an audio reduction (pad) scheme when headphones were inserted to help protect young ears.

3. Thinking about loudness early in production helped the team work more effectively toward that goal, but also helped simplify audio production in general.

4. Instead of simply ducking music anytime dialog plays, they decided to map the experience in two zones: player listens, player interacts. The music becomes more subdued (while keeping the same basic song structure) whenever dialog plays. This not only makes it easier to understand the dialog, it guides the player through the zones with an audible prompt. The subtle music tells the youngster it’s time to stop and listen. The return to the more active version of the music is the prompt to interact again. It’s an elegant audio design for user experience.

5. Some mobile users are going to wear headphones. Others are not. The audio presentation must work in mono on a tiny speaker. And on headphones.

6. Media made for kids should actually consider two audiences:
(1) The experience the child has, and
(2) The direct experience the parent may have, or indirect experience while the child interacts.
So the content — including audio — should engage the child, but also feel safe and fun for a parent.

7. “Consistent dialogue levels, clarity and performance were especially important for our design in terms of communicating the educational and instructional aspects of the experience so audibility and intelligibility at all times were critical.” But without sacrificing the fun! Balancing learning with entertainment rings true with my experiences in all educational media for kids. Sesame Street is so much better than a character shouting curriculum at the fourth wall.

8. In iterative build reviews they subtracted any dialog that was neither educational nor fun. This helped remove audio clutter, for a more focused user experience.

Throughout the post-mortem, Rob’s focus on possibility and opportunity — rather than limitations and problems — was the single most inspiring aspect of the entire article. Moving quickly from adversity to opportunity is more than just a positive way to view a situation. It’s a recipe for adding value to almost any situation, individually and as a team. So here’s to better audio as we anticipate opportunities to use these lessons from Rob.

Be inspired for yourself. Read the entire article.

Nasty ProTools Errors

It’s interesting to know what limits and problems other people are having with the same tools I use. Here’s a collection of responses from Twitter and Facebook when folks were asked what ProTools errors they found especially troubling:

“Pro Tools did not shut down properly. You must restart your computer.” – @grhufnagl
“ProTools has quit unexpectedly…” – Preston Shepard
“that would probably be this one” – @insomaniac
ProTools error dialog box with no text
ProTools 11 is “a vast improvement in many ways (not video!).” – @JamieMusicNYC
“For no reason PT sometimes just come up with def prefs. Even daily.” – @tamasdragon
“Check this crash bud….It didnt come with an error number….lol… ” – @lobbyshifter

A few weeks ago my colleague @SwiftyMorgan told me about this one: Neo Assertion in [volume name], line 164

ProTools Sync: The Short Video Problem

I mistakenly assumed this issue was fixed several versions ago, but I’ve seen it again recently in ProTools 10. It could be caused by code deep in the video playback core of the software. It could even be caused by some quirk with Quicktime, which ProTools uses for the video decode heavy lifting. I’m documenting it here in case anyone else encounters it — it can be difficult to diagnose and sometimes isn’t simple to solve.

This error occurs when the video file is shorter than the audio. In other words, audio extends past the end of the video. Then audio is highlighted in the Edit window and a Bounce to Quicktime command is issued. For whatever reason, sometimes the video is stretched — frames are added or lengthened — so that the length of the video and audio are the same.

Video clip shorter than audio causes error

This is a huge problem for several reasons:
The audio and video drift out of sync getting worse toward the end.
The video may look strange, or in extreme cases, terrible.
There is no error message or indication during the Bounce. You have to review the video outside of ProTools to find the problem.

Video sync can tricky, both in terms of the mistakes we can make because we’re human, and because ProTools is an audio-centric tool that also allows video. The plethora of video codecs makes testing every permutation a challenge for software developers too. Given the number of other things that can go wrong, the short video problem feels especially insidious.

1. Don’t combine the video and audio using ProTools; don’t bounce to Quicktime.
2. Pad the video at the end.
3. Cut the audio to end as soon or sooner than the video.

A good social media feed should bring inspiration, good things to read, and a bit of fun. But too often a stream can get crowded with irrelevant posts, marketing, and drivel. Facebook likes to filter for us (no thanks), but it takes some discipline to prune an overgrown Twitter or Google Plus feed. Once committed to some cleanup, who should be cut and who kept?

I like to read about professional audio, game design, voice acting, and other topics related to my profession. I’m not opposed to personal posts now and then, but I primarily want social media to feed my brain and help keep me enthused. The curated feed of Women’s Audio Mission is amazing in this regard (on Twitter and Facebook). All of the posts are audio related. I’d miss so much good stuff if I didn’t follow WAM.

I adore the work of science fiction writer William Gibson and was elated to find him on Twitter. But he posted so much stuff I couldn’t keep up. I held on for months out of respect for his Cyberpunk novels, but eventually had to admit that his Twitter profile just wasn’t a good fit for my social media personality and habits. I seem to prefer people who post occasionally, and when they do post, it’s good stuff that gets right to the heart of things.

The difference between social media and broadcast media is the willingness for conversation. If I’m following someone who is just blasting out promotional material about their projects, but doesn’t engage in conversation, I might as well be watching TV or listening to radio. I’m looking for people who want to help each other find solutions. I’m interested in folks who are building community. For example, guru of #GameAudio Lost Chocolate Lab nurtures our community with his posts.

I don’t tend to watch video or listen to much audio on my mobile. When posts are predominantly text and pics I can catch up while waiting for coffee or food. That’s not to say I don’t enjoy watching or listening, but I’m not prone to do that mobile – where I typically engage with social media. (If something high bandwidth seems really good, I save to Evernote and check it later on a good screen and better audio reproduction).

Who do you follow and why?

Good Names, Bad Names…

… you know I had my share. Previously we explored ways to let people know more about a media file using metadata, a ReadMe doc, a posting notification, folder name, and file name. Here are a few more tips for creating good file names and avoiding bad ones.

At the time you name a folder or file, the word “new<" may be accurate and descriptive. But after some time passes, the content will no longer be new. Worse yet, if another version is needed after that, “new” in a previous file name is downright confusing. Because there may be more than one version of an audio file, using the word “new” should be avoided.

For the same reason “final” is a terrible choice for a folder or file name. Using “final” is like a curse on your file, inviting someone to request another change. To prevent names that are ambiguous — and especially wrong — be sure to avoid using “new” or “final” in folder and asset names.

A simple and common way to distinguish files for version control is to use an incrementing number. For example: SmRoomAmbLoop_Stereo_vers1, SmRoomAmbLoop_Stereo_vers2, etc. If you are creating every version, or you administer the naming, then a simple incrementing version number can be a great way to keep track of everything.

When large teams are working simultaneously on a project, it may be difficult to know the current version number. Using the date may be helpful especially if many iterations are anticipated.

Workflow Milestones

It’s often useful to know how far along an asset is in the process. Inserting words like scratch, raw, edit, master, and the like identify where the asset relates to major milestones in the workflow. This is valuable during production when there are fixes, and also if someone wants to revisit a project (think sequel) months or years after the initial project has been completed.

There are often major categories of audio file types such as dialog, music, and effects. These can be important file groups to call out by including right in the name. When assets are organized into folders by these categories, the folder name is an obvious place to use these words. But when files seem likely separated from your folders, the categories may better be used in each asset name. An abbreviation may be helpful for adding category to a file name.

Don’t overlook combined use of version number, date, milestone, and category in a file name. For example: fx_SmRoomAmbLoop_v3_2014-01Jan-02_edit.wav may help any number of people downstream quickly recognize and make effective use of the audio.

Frozen Storybook Deluxe

We had so much fun making the Frozen Storybook Deluxe app. Editor Vickie Saxon placed a special challenge before narrator Kari Wahlgren: tell the story from the perspectives of both sisters Elsa and Anna. Not only did she give a phenomenal performance, I grinned all session long as Kari wove nuance and subtext into this telling of the story. At various points during the narrative readers can choose to rotate the device for the other sister’s viewpoint, keeping the experience fresh and unique.

Kudos to producer Ashley (Kaye) Bravo for marshaling the efforts of our design, animation, and audio teams in coordination with the developer to make this beautiful app.
