There are some amazing things in Mac OS X, both in positive and in the negative. On the one hand, here are great features, applications, and really well done.
Just think of iMovie, just as an example: it is one of the best, and simplest, video editor for mac, and also free of charge.
But if we iMovie with Mac OS X completely lacks a good audio editor. Getting all things simple, how to create a ringtone from an MP3 file, merges several audio tracks to WAV or adjusts the bass of a song, all things that now you can also do with an iPhone application, none of this is provided by Mac OS X.
The only way to achieve this is to use an audio editor for mac produced and distributed by someone else. Fortunately, some of the best do not cost an arm and a head, and you can have them for free.
Audacity
I think it is the best audio editor available for Mac OS X, and it is a completely free and open source. Audacity can handle audio files, including uncompressed, type WAV, AIFF, FLAC, MP2 / 3 and OGG. In addition to the basic operations of an editor can be used to analyze in detail each file also thanks to a simple but complete. Audacity can also be used to record audio from various sources, both from an external microphone by audio on your Mac. The only thing that might be a bit complex is precisely the configuration of the audio sources. There are plug-ins can be downloaded from a site, which greatly simplify the steps you should take.
WavePad
WavePad is a free program, if you intend to use it to develop, merge, split and improve their files. If you are going to make a commercial use, then prompted for a license to use about $60. What is an affordable price because you can work on many files at once, and grace to support batch file can also modify hundreds or thousands of songs automatically. The interface is still simple and suitable for those who have few requirements and is satisfied with the essential operations. But as soon as you go a bit deeper you will discover a lot of potential perhaps more appropriate to use a semi-professional amateur one at that.
OcenAudio
OceanAudio is a Brazilian project, and is both free and cross-platform. It very powerful, versatile and with some rather unique features. It obviously gives the possibility to apply filters, sound effects and cut, but there are two aspects to be emphasized. The first is that, due to good management of the memory can be used to edit audio files even very large without the risk of slowing down the computer, or clog the memory. Indeed, it is one of the editors faster when it comes to working on file’s giants, or on many files simultaneously. But there is also another thing to note: OceanAudio allows you to select multiple audio clips simultaneously within the same track, and to work on together. This is really a good thing, especially when you have to repeat the same steps several times on the same track.
Fission
Finally, there Fission audio editor for Mac as a very simple and fast program that offers not many possibilities when compared with the previous ones, but that is suitable for those who want an agile program. The sound quality is decent final in the free version, but there is also a paid version (costs about 30 euro) which allows you to have modified files of excellent quality. The tools available are the same in both the free version in that fee, the only distinction is the quality of the results that can be achieved.
