Audio Ease - BarbaBatch - Supported Filetypes - Microsoft (MS)ADPCM
This type is mainly used on PC's and was created by Microsoft.
The standard file name extension for this soundfile type is ".wav"
Wave 32 bit float
This very high quality format is used by a.o. SEKD Samplitud, SADIE and Nuendo software and for archival purposes. BarbaBatch can also write 32 bit floating point data to Quicktime Movies.
8 bit CCITT u-law data in Wave files. Mostly used in telephony applications. Common samplerates are 6000 Hz and 8000 Hz.
8 bit CCITT a-law data in Wave files. Mostly used in telephony applications. Common samplerates are 6000 Hz and 8000 Hz.
Generally a high perceived level is needed in u-law and a-law files as well as a dramatically low dynamic range. We suggest you use the BarbaBatch look ahead peak limiter in conjunction for this conversion with a setting like this:
The Microsoft ADPCM file is a WAV file that contains data that is compressed using a technique called Adaptive Differential Pulse Code Modulation.
This method packs every 16 bit or 8 bit sample into 4 bits while maintaining a surprisingly high fidelity. Support for real-time playback is in the Windows 95 operating system And in Quicktime 2.5 on the mac.
If any audio producer requires you to deliver 22khz 8 bit audio, do consider offering this format instead. Old systems can play it, it takes less space, and very little resources.
