What versions of the Windows OS is Alto Studio compatible with?
Alto Studio works on any Windows version from Windows 7. It has been tested and works
well on Windows 8, 8.1 and 10.

Is there a Mac version?
Alto is currently only available for Windows. However, it has been tested and works
perfectly with Boot Camp and Parallels on Mac. In addition, we are also planning to make aMac version in the future but we cannot provide any estimation for the release date at thispoint.

2What audio file formats does Alto Studio support?
Alto Studio can read audio files in the following file formats: Wave, AIFF, MP3, Ogg Vorbis
and Flac.

Can Alto Studio analyze / correct a very large number of files?
Alto Studio is being regularly tested with very large numbers of files (i.e. more than 100 000).
We make sure that no resources are getting low while processing such amounts of data andthat there are no memory leak. Many of our customers are dealing with very large projects
so it is a high priority for us to ensure that there is no problem in that regard.

Can Alto Studio work with a single language or multiple languages?
Alto Studio can either analyze and correct the audio files in a single language or compare
files in multiple languages and match them with reference files.

How long does Alto Studio take to analyze X files?
It will depend on the number and duration of the files, the type of the analyses you want toperform as well as the specifications of your machine. The following table shows someexamples of benchmarks (they were done with Alto 2.1).

Simply checking that the files are present in all languages is very fast. Checking their audio
format (bit depth, sample rate and number of channels) or their total duration is still very
fast, as only the header of the files has to be checked.
The audio data itself must be analyzed when checking for leading and trailing silences, aswell as for the loudness analysis (integrated, range and peaks), which takes a bit more time.
The spectral analyses (e.g. average pitch) can also be time-consuming as they require thecalculation of Fast Fourier Transforms (FFT) on the signal. However, these analyses are
rarely necessary. Of course, it also depends on various factors such as the other tasks
running at the same time, the amount of memory available and the machine configurationin general.
Alto Studio leverages multi-core processing to achieve faster analysis times. So the morecores you have, the faster the analysis will be. Because the type of processing that Alto
Studio performs is well suited to this kind of optimization, the speed can literally bemultiplied by a factor close to 2, 4, 6 or 8 etc… depending on the number of cores of yourprocessor.

Does Alto Studio support dialogue in the <X> language?
Alto Studio does not require a special knowledge about the languages themselves.
Therefore it can be used with dialogue in any language. Although it comes with some helpfulpresets for FIGS, CJK, ZPHR and PTB (only used for the organization of the files), you candefine your own languages and even add Klingon if you want!

Does Alto Studio support my game audio middleware?
Alto Studio can import dialogue lines from all the major game audio middleware: ADX2 from
CRI Middleware, Wwise from Audiokinetic, Fmod Designer from Firelight Technologies andFabric from Tazman Audio.
Alto Studio can also export data to Wwise and ADX2. The audio files will be imported into
the project, the new languages added if needed, and the work units and containers
automatically created, with user-specified parameters applied. Script lines and characternames can also be inserted in the comments.
If your audio middleware is not supported, please contact us and we will try to add it.

If you are using an internal game audio engine or a proprietary dialogue database, we canalso develop a custom importer for you or your programming team can do it by writing an
Alto Studio plug-in.

How can I develop my own importer / exporter / tool plug-in?
If you want to interface Alto Studio with your own proprietary dialogue tool or database, or
if you want to extend its feature set, you can write a C# plug-in. Please refer to theintegration notes available here:
http://www.tsugi-studio.com/Support/Alto%20Integration%20Notes.pdf
It is very easy and the GUI can be generated automatically for you. If you want to go ahead,please contact us at the following address to get the full SDK: support@tsugi-studio.com

In what format does Alto Studio publish reports?
Alto Studio reports can be consulted within the tool itself. In addition, Alto Studio canpublish the analysis reports in PDF, HTML and XML and also as Excel worksheets. When thereports are saved as an Excel worksheet or a set of HTML web pages, links are added thatallow you to play the audio files referenced by clicking on them.

Where can I find more information about Alto Studio?
Various documentations, tutorials and videos can be found on Alto Studio’s web page:

Alto Studio is missing a feature I need, can you add it?
We are always looking to improve Alto Studio and to make it meet your needs. Therefore,
we are thrilled when you take the time to contact us at support@tsugi-studio.com tocommunicate your ideas and we will definitely reply to you.
In general, when you need a new feature, there are 3 possibilities to get it:Contact us and if the feature is of general interest and we are qualified to add it, it willfind its way into a future version of Alto Studio.
Ask a programmer on your team to write a plug-in using the Alto Studio SDK that does
exactly what you want.
Ask us to develop the plug-in for you or to build a customized version of Alto Studio foryour company. This usually turns out to be relatively cheap and fast as many of thefeatures you may need are usually already present in some form somewhere in the Alto
Studio code base. So don’t hesitate to contact us!
