What is the .EFV File Extension?

.EFV File Extension Description:

The Ensoniq Corporation developed the digital synthesizer model VFX-SD. Creative Technology bought the company. Creative Technology then fused Ensoniq with another company it purchased called E-MU Systems. At the beginning, E-MU Systems maintained support for some of the products distributed by Ensoniq, including the Ensoniq VFX-SD digital synthesizer. However the company eventually discontinued distribution and support for Ensoniq products.

The EFV file extension is used to store projects created on the Ensoniq VFX-SD digital synthesizer. Using samples and effects uses digital synthesizers to create music. Samples can contain different kinds of sounds such as instrument emulations, digitally created effects and sung portions. The audio projects created with the synthesizer are given the file extension .efv.

Files with the .efv file extension are used to store music files. The Ensoniq VFX-SD digital synthesizer strings together samples and modifies them and saves them with the EFV file extension. Users can still edit files with the EFV file extension without making any changes to the compression. This is because files with the file extension .efv are project files. File format converters can still translate files with the EFV file extension so that other audio programs can use them.

Ensoniq digital synthesizers were designed so that the user will create only one line of the instruments. Because of this, the user can only use files with the .efv file extension with the Ensoniq VFX-SD synthesizer. The device can then output the audio files into other formats if they are finished.

The EFV file extension is used to identify audio project files of the VFX-SD synthesizer. These project files contain the actions used to make and edit the audio project. The user can still change several things with files saved with the file extension .efv.

Files with the .efv file extension can contain a combination of samples. The samples can already be looped, modified or connected. Project files can also be used to store incomplete and unfinished audio tracks.
