免費線上 DV 轉 SPH 轉換器

DV is a digital format of magnetic video recording and a type of video compression developed by the major video equipment manufacturers in 1995. The DV format uses an 8-bit digital component video signal with a resolution of 720x576 pixels. Data transfer is made in the form of a DIF-sequence that contains video, audio and subcode data. Date and time are recorded in the service area.

SPHERE (SPeech HEader Resources) is a file format defined by NIST (National Institute of Standards and Technology) and is used with speech audio. SoX can read these files when they contain μ-law and PCM data. It will ignore any header information that says the data is compressed using shorten compression and will treat the data as either μ-law or PCM. This will allow SoX and the command line shorten program to be run together using pipes to encompasses the data and then pass the result to SoX for processing.
