exclusively as DualDiscs. Costs versus conventional CDs In the United States, the cost of a DualDisc at retail versus that of a conventional CD varied depending on the title but, on average, a DualDisc cost about $1.50 to $2.50 USD more than the same title on CD. Some DualDisc titles such as Mr. A-Z by Jason Mraz and In Your Honor by the Foo Fighters had enhanced packaging which increased the retail cost of the DualDisc version of the albums over their CD counterparts more than the average. There were also other factors which go into the additional costs such as production, marketing etc. Common DVD content What one finds on the DVD side of a DualDisc title will vary. Common content includes: The entire reprinted album (and possibly bonus material) in higher-quality stereophonic and/or surround sound.

Audio types The CD side of a DualDisc contained standard 16-bit LPCM audio sampled at 44.1 kHz. On the DVD side, most record companies (with the notable exception of Sony Music: see below) provided the album's music in both high-resolution, 24-bit DVD-Audio (typically at a sample rate of 96 or 192 kHz for stereo and 48 or 96 kHz for surround sound) and lower-resolution, 16-bit Dolby Digital sound (typically sampled at 48 kHz). This was done to allow consumers with DVD-Audio players access to very high-resolution stereophonic and/or surround sound versions of the album, while also providing the lower-resolution Dolby Digital stereophonic and/or surround sound which is compatible with any DVD player. Sony Because Sony had an existing high-resolution audio format, SACD, in the marketplace which directly competes with DVD-Audio (see next section), Sony Music, as a general rule, only provided 16-bit, 48 kHz sampled LPCM stereophonic (and sometimes Dolby Digital Surround) sound on the DVD side of their DualDiscs. The sound was compatible with any DVD player; however, it does not provide the higher fidelity and resolution of 24-bit, high sample-rate DVD-Audio. In addition, several SonyBMG titles whose regular editions include copy protection programs (such as XCP and SunnComm) did not feature the software on the DualDisc versions. Competition The biggest competition to DualDisc was the hybrid Super Audio CD (SACD), which was developed by Sony and Philips Electronics, the same companies that created the standard CD. DualDiscs and hybrid SACDs were competing solutions to
