LEAD Audio SPDIF Passthru DirectShow Filter |
| |
The LEAD Audio SPDIF Passthru filter is a DirectShow filter for passing AC3 (Dolby Digital) or AAC (DTS) surround sound signals to an S/PDIF audio renderer.
The LEAD Audio SPDIF Passthru filter passes surround sound signals including 5.1, 6.1 and 7.1 to external devices, such as surround sound systems or home theater receivers, that are capable of decoding a Dolby Digital or DTS signal.
Play AC3/AAC Encoded Files Without a Software AC3/AAC Decoder
When used in conjunction with an external device capable of decoding AC3 (Dolby Digital) or AAC (DTS) files, the LEAD Audio SPDIF Passthru filter makes it possible for a user to play AC3/AAC files without a software AC3/AAC decoder. Without either the external device or LEAD Audio SPDIF Passthru filter, the user will need a software AC3/AAC decoder to play AC3/AAC encoded files.
Better Sound Quality
If speakers are connected to a external device capable of decoding a Dolby Digital or DTS signal, passing the S/PDIF signal to the external device provides higher quality audio because the external device decodes the audio to preserve the surround effect. Software decoding without passing the S/PDIF signal to an external device will often generate only stereo sound, even if the audio source is surround sound.
