1. Audacity: Audacity is probably the most widely used and free audio recording software programs, capturing the hearts of both sound engineers and casual audio mixing crowd. It can be used for audio recording from microphone, file conversion, cutting, copying and editing sound files. Its supported audio file formats include MP3, WAV, AIFF and OGG Vorbis. The Beta 1.3.13 is its latest version, that is now appropriate for windows 7, Windows Vista and Mac OS X 10.6. The fine particles are mostly made from gases. There are four major origins for that gases which are responsible for these particles: rock (vaporized during combustion or casting), carbon from combustion, organic carbon, sulfates and nitrates. Take sulphur dioxide. It is created during engine combustion, but when it climbs into the atmosphere and mixes with rain it will become sulphuric acid. We all probably know very well what that will do- since it is highly corrosive and dangerous in concentration. Incidentally, drag race aficionados have a well-bred desire for the antiquities with their considerable curiosity about vintage and classic cars. Old fashioned and strange because they may seem on the outside of, these cars are highly esteemed for sturdy body built and fit streamlining which is way beyond some of our modern car?s durability in time of collisions and bumps.
