Many developers wonder if they can get the raw PCM data back from OpenAL. This would be convenient for things like drawing oscilloscopes or spectrum analyzers. The answer is no. The reason is that OpenAL was designed for performance, and thus OpenAL is free to mutilate the data you provide, if it will help performance in any way. This part of the spec was geared more toward vendors implementing hardware acceleration for OpenAL (such as Creative Labs). Requiring the spec to be able to return the original data created undue burden for these implementations. For those now wondering how you would build an oscilloscope with OpenAL, the solution is inelegant: Keep your own copy of the data and run your own timers to infer where you are in the buffer. Yes, this is kind of painful. You might be able to skip the timers with streaming if you care less about accuracy. We ll do something kind of related in 12, so stay tuned.

The Oracle Text schema is CTXSYS, which will be preloaded into the Oracle Collaboration Suite database This schema has the relational tables and indexes derived from the nonrelational data that has been indexed, and the procedures and functions used to manage the indexes For instance, the package CTX_DDL has procedures for defining the rules to apply when indexing documents, and the package CTX_QUERY can execute queries against the indexes All the Oracle Text facilities require use of what is known as a lexer A lexer defines the way the text data is structured and is necessary to allow Oracle Text to parse the data correctly It will include rules for such.

We now have both an OpenAL data buffer, which holds our sound data, and an OpenAL source, which can play sounds. The next step is to connect the two, so when we finally tell the sound source to play, it knows which sound data we want. In the initOpenAL method in OpenALSoundController.m, append the following line:

Some image formats let you adjust settings to trade quality for smaller file size. In some cases (for instance, small buttons on a web page), it may be important to make the file as small as possible, and a slight loss of quality may be worthwhile. JPEG and GIF both have quality adjustments, but their methods are very different.

alSourcei() is a generic OpenAL API function that sets properties on OpenAL sources. The first parameter is the source ID of the source you want to manipulate. The second parameter is a constant that states what kind of operation you want to perform. In this case, we are connecting a buffer to our source. The final parameter is the buffer ID. After we call this function, unless we make any more changes, any time we want to play this source, it will use this attached buffer. We do this in our initOpenAL method because, for this example, we don t plan to change sounds.

things as word breaks and how to handle case and accent variations, the language, and much more Oracle Text ships with lexers capable of managing both European and Asian languages The default tablespace for the CTXSYS schema is the SYSAUX tablespace If extensive use is made of Text, this schema can expand to a significant size, perhaps several gigabytes The database administrator should monitor the size of the CTXSYS schema, and if necessary move it to another specially created tablespace This query will show how much space is being used by Oracle Text: select space_used_kbytes from v$sysaux_occupants where occupant_name='TEXT'; This procedure call will relocate Oracle Text to another tablespace (which must have been created already) called CONTEXT: execute ctxsysdri_move_ctxsys(tbs_name=>'CONTEXT'); Unlike normal relational indexes, Oracle Text indexes need not be maintained in real time.

JPEG s quality adjustments come by varying the amount of image compression. JPEG s compression takes advantage of tricks of human perception; it tries to degrade quality in ways that won t be very noticeable. By experimenting with the Quality setting in the Save as JPEG dialog (Figure 2-5), which appears after you specify a file name ending in .jpg, you can find a balance that gives you a very small file size but still a pretty good-looking image.

We are finally ready to actually play a sound! We are going to write a method called playLaser, which will encapsulate this. This is not clean design, but convenient to quickly finish this example.

Create the following method in OpenALSoundController.m:
