Free audio format software for mac

PSD Format 1.0 is known as a simple yet useful shell and desktop tool. PSD Format reads Photoshop document format files and converts them to presets. The preset lists can be modified, deleted, rearranged and saved as "Default New Doc Sizes.txt" files.

AudioLobe 4.2 is designed to help you independently alter the playback speed and pitch rate of audio files. If you are a musician or interested in audio this means you can slow down complex sequences of audio without the vocal or instruments sounding unintelligible. Great for learning difficult notes in a musical sequence.

For example, you could set a section of the audio to loop at whatever playback speed you want and easily follow what is happening, without having pitch changes. AudioLobe 3 allows files to be saved with altered play speeds and major update update to the interface.

Major Features:

1. Alter playback speed and pitch independently.
2. Save audio/video with altered playback speeds to new files.
3. Drag and drop playlist.
4. Easy to use and intuitive audio controls.
5. Supports all the common audio and video formats.
6. Major update to the graphical appearance.
7. Displays detailed audio track data.
8. Autosaves column width changes and positions, new preferences for color control.
9. Separate window for audio indicators and audio power levels.
10. Many minor improvements for list clearing, software updating, control sizes, help menu, etc.
11. Full-featured demo version. Saving of altered-speed audio files available with $20 license.
12. Play adjusted-rate audio/video files exported by AudioLobe in other free apps such as QuickTime, ReelBean, etc.

M-Audio Midisport 8x8/s adds support for this device on Mac OS X.
Enhancements:
- Added support for both Power PC and Intel-based Macintosh computers.

AudioSlicer is a nice Cocoa tool that finds all silences in an audio file and allows you to split it into several smaller audio files and to name/tag them properly. For now only MP3 is supported but other audio formats may be added in the future.

While most other tools doing this split automatically according to certain criteria,
AudioSlicer shows you all silences within a certain range of duration.

You can then listen to the silence - well, to the audio before and after the silence really - and then you decide if you want to split there.

The splitting is done without loss, there is no decoding and re-encoding of audio data taking place.

MOTU Audio System (MAS) 2.4 is a highly-efficient, high-quality DSP plug-in format that powers Digital Performer, Performer and AudioDesk. While ASIO drivers that work with MAS are included, this is really a minor issue.

FMOD is a cross platform audio library that supports a wide range of audio formats and playback options, including a physically correct 3D audio engine. The FMOD Ex Audio Classes leverage FMOD to create a simple but powerful audio interface for REALbasic. Note however, that these classes do not expose all of FMOD Exs functionality, nor are they wrappers to access the FMOD Ex API directly.
First, a little background... The FMOD Ex API supports multiple concurrent "system" objects which may map to multiple audio devices installed on the same machine. Consequentially, all audio samples, channels, and effects are owned by a single system object and can not be shared. If a system object is destroyed, all sounds, channels, groups, and effects created under that system become invalidated and accessing them will generate errors (or worse).
To simplify this situation within the REALbasic environment, these classes do not allow for more than one system object to be active at any given time. Under normal circumstances this should not cause any grief - you call FMEx.StartUp when your application is launched, load your audio samples, create player objects, etc., then call FMEx.ShutDown when your application quits and all will be fine. If you have a need to restart FMOD Ex however, all existing FMExAudio, FMExStream, and FMExSubMixer instances will point to invalid audio handles. There is error checking in place to avoid crashes if this situation should arise, but it can still be annoying. In order to properly restart FMOD Ex you should follow the steps below...
Call the Stop method on all existing FMExAudioPlayer and FMExAudioPlayer3D instances. You do not have to dispose of these objects, but calling Stop ensures the internal channel reference is reset.
Dispose of all FMExAudio, FMExStream, and FMExSubMixer instances (i.e. set them to Nil). Be sure to also dispose of any FMExAudio instances that have been assigned to FMExAudioPlayer.DefaultAudio properties.
Call FMEx.ShutDown, followed by FMEx.StartUp, then reload/recreate all required FMExAudio, FMExStream, and FMExSubMixer objects and re-route any submixers.
ByRef methods are provided to allow you to reuse existing FMExAudio, FMExStream, and FMExSubMixer instances by replacing the required data/handles. This can be much easier than recreating them from scratch.
These classes couldve been simplified further by automatically reference counting audio objects and starting/stopping FMOD Ex behind your back, but that would preclude the ability to restart the audio engine at any time, and greatly impair the start up options interface.
- Virtual Channels
One of FMOD Exs most touted features is automatic channel virtualization. This allows you to play sounds on more channels than are physically available and let FMOD Ex decide which are more important based on priority settings and 3D positioning. One caveat with virtualization is that you must call FMEx.Update as frequently as possible for this to actually work (e.g. in games youd typically call FMEx.Update every frame). NOTE: If youre already calling FMEx.Update for 3D audio you do not need to call it twice.
- MIDI
MIDI playback currently only works on Windows, and only if the default system sound font is installed (/windows/system32/drivers/gm.dls). Broader MIDI support is on the would-like list but primary tests point to a broken implementation on Mac OS X (i.e. some FMOD Ex bugs need to be fixed before this can work).
- Other bugs...
Stereo sounds routed to submixers may "pollute" the wave data of other submixers. Everything else works as expected however and the audio output is correct, but submixers may return incorrect values when calling their Level methods. This appears to be a bug within FMOD Ex itself but more testing is required.

Enhancements: Version 1.52: Intel/PPC Check update.

Requirements: Mac OS X 10.4 or later.
