Shine MP3 Encoder on Alchemy

Shine (formely 8hz-MP3) is a simple lightweight C-based MP3 encoder made by LAME developer Gabriel Bouvigne.

Description of Shine on his website:

The goal of this encoder was not quality, but simplicity. I tryed to simplify the encoding process as much as possible. So Shine is then a good starting point when a programmer needs a very simple MP3 encoder

This Alchemy port features:

MP3 encoding of mono and stereo WAVs (no time limit)
non-blocking encoding for progress status in flash
errors automatically sent to flash for easy log/debug

WAVWriter.as

Helper class to write WAV formated audio files. The class expects audio input data in a byte array with samples represented as floats.

The default compressed code is set to PCM. The class resamples and formats the audio samples according to the class properties. The resampling geared for performance and not quality, for best quality use sampling rates that divide/multiple into the desired output samplingRate.

For more information about the WAVE file format see: http://ccrma.stanford.edu/courses/422/projects/WaveFormat/

Flex Builder 4.5.x Test Drive for Mobile Tutorials

Here is a very good multi-part tutorial on the ins and outs of mobile client / server development, that adds some quite useful functionality on Android, Apple IOS and Blackberry mobile devices.

In this Test Drive, you are going to create a Flex mobile application that retrieves, displays, and modifies database records (see Figure 1). A Flex application does not connect directly to a remote database. Instead, you connect it to a data service written in your favorite web language (PHP, ColdFusion, Java, or any other server-side technology). You will build the front-end Flex mobile application; the database and the server-side code to manipulate database records is provided for you as a PHP class, a ColdFusion component, or Java classes.

Data paging with Flex and PHP using Flash Builder 4.5.x

Flash Builder 4.5 has a built-in data paging feature that generates ActionScript code to retrieve data from the database incrementally on demand. For example, suppose your database has thousands of records and you want to fetch only 20 rows at a time and display them in a data grid. When you enable paging for an operation and bind the operation result to a DataGrid control, the first 20 records will be retrieved initially and the next page of records is fetched only when the user requests them—that is, when he or she scrolls the vertical scroll bar of the DataGrid control.

Flash Builder 4.5 lets you enable paging for any type of data service operation including operations on a Remoting service, web service, or HTTP service. This article explains how to enable data paging for a PHP-based Remoting service. After you set up the server environment required for the sample application, you’ll use Flash Builder 4.5 to generate ActionScript service classes and build a Flex application that incrementally retrieves data sets from a database table using the PHP class on the server.
