Source of an example to play a WAV file in the background and be sent a message when its finished playing. This example was derived to overcome the deficiencies of using just the 'sndPlaySound' function. The 'sndPlaySound' is ideal and easy to use to play WAV files synchronously. It allows asynchronous playing of WAV files as well, but there is no method of notifying the host when the sound has completed playing. This example was put together after studying the MMSYSTEM.PAS unit, and articles on the MSCDN.

Description

"MP3 Info & Convert" is a tool to display information about MP3 audio files. To do so, just drag a file from the explorer and drop it on the text control.

Additionally, correct MP3 files can be converted to WAVE files using the MP3 audio codec by prefixing them with the according RIFF WAVE header. This process is fast and lossless (no re-encoding) and creates a file of the same name but with the extension WAV in the same folder as the original file. To do so, just click the button "convert to wave / res" in the lower right corner of the window.

Alternatively, the result of this operation can be directly embedded in a RES resource file. This can also be done by clicking that button.

After conversion, these files can be embedded into projects as resources and be played directly (without extraction) using the API "PlaySound" function. See the application's source for an example.

Getting a large JPEG loaded into a TImage component can sometimes be very slow. Think about decompressing a 5.5Mb file to 24Mb of data and getting that into the image and you can understand why. Try resizing a large multi_MB JPEG image to a thumbnail using standard resampling or resizing techniques and see just how long it takes.

In order to reduce that time, I've been delving into the use of the JPEG Scale option which, with a tweek or two, can considerably improve that time. There are a few items about it on the net but I believe it deserves more prominence.

The attached simple application is my offering on the subject. Have a look at the code to see how Scale is used.
