Usually commercial software or games are produced for sale or to serve a commercial purpose. Even though, most trial software products are only time-limited some also have feature limitations. After that trial period (usually 15 to 90 days) the user can decide whether to buy the software or not. Trial software allows the user to evaluate the software for a limited amount of time. Demos are usually not time-limited (like Trial software) but the functionality is limited. In some cases, all the functionality is disabled until the license is purchased. Demoĭemo programs have a limited functionality for free, but charge for an advanced set of features or for the removal of advertisements from the program's interfaces. In some cases, ads may be show to the users. Basically, a product is offered Free to Play (Freemium) and the user can decide if he wants to pay the money (Premium) for additional features, services, virtual or physical goods that expand the functionality of the game. This license is commonly used for video games and it allows users to download and play the game for free. There are many different open source licenses but they all must comply with the Open Source Definition - in brief: the software can be freely used, modified and shared. Programs released under this license can be used at no cost for both personal and commercial purposes. To create your own Audio Field-guides for RememBird, you will need to download the Lame MP3 Encoder. Open Source software is software with source code that anyone can inspect, modify or enhance. WMA9 is VASTLY superior at these lower compression factors. I read that LAME 1.98.1 is an excellent MP3 encoder, however, thus far, compared to WMA9, particularly at 128Kbps and below, LAME 1.98.1 is just that - lame. Freeware products can be used free of charge for both personal and professional (commercial use). But its the ENCODER that I am most interested in. Note: The download is a compiled LAME MP3 binary (not a source code).įreeware programs can be downloaded used free of charge and without any time limitations. MP3x: a GTK/X-Window MP3 frame analyzer for both.For WAV and AIFF input files, using -m will always produce a mono. Fast! Encodes faster than real-time on a PII 266 at the highest quality mode. To encode a stereo PCM input file as mono, use lame -m s -a.
