How many GB is a CD-R?
Expressed in binary notation (as is typical with CD-R, CD-RW and most operating systems) the same disc has a capacity of roughly 4.38 GB [4:700,000,000 bytes ÷ 1024 = 4,589,844 KB ÷ 1024 = 4,482.27 MB ÷ 1024 = 4.38 GB] . How much information can actually be stored on writable DVD discs?

How many bytes is a CD?
2,352 bytes
What is the largest CD capacity?
Largest Capacity The largest CD-R discs manufactured are 99-minute CD-R discs. For storage, these discs are capable of holding up to 870 MB of data.
Is HD audio better than CD?
High-Resolution Audio is audio that uses a higher sampling rate than in CDs and MP3s for the encoding and playback of music. High-Resolution Audio files have a sampling frequency of 96 kHz/24 bit, which is significantly higher than the 44.1 KHz/16 bit sampling frequency of CDs.
Is 96kHz better than 48kHz?
There’s much debate whether sample rates higher than 44.1kHz, like 96kHz or even 192kHz, yield a significant sonic improvement. According to many people, higher sample rates aren’t necessary. Yet others insist higher sample rates are audibly better.
Should I record at 192kHz?
For mastering, 96kHz or even archival mastering at 192kHz is usually a good idea. Regardless, recording at 44.1 or 48kHz through a high-quality modern audio interface will give you excellent results, depending on the situation, very similar to what you’d get at higher rates.
Does 24-bit sound better?
24-bit is “better” for pro audio recording and mixing in that it allows for a greater dynamic range. In other words, there’s way more room at your output bus before you clip. You then dIther down to 16-bit for most listening situations. Bit-depth does not affect frequency bandwidth.
What sample rate is best for recording?
Research has shown that recording your audio at a higher sample rate (such as 48KHz or 96KHz) and then dithering it back to 44.1KHz doesn’t improve the sound of the recording and even cause slight distortion. We highly recommend recording your songs at 44.1KHz.
Is 48khz enough?
So there you have it, the answer to the age old question: “Is 48 kHz enough?” – and the answer to it is “No”. The minimum necessary to accurately reproduce most real world audio is 96 kHz, and some things even need 192 kHz or higher to be correctly reproduced.
Is there an audible difference between 44.1 and 48?
There is now no difference between down-sampling 48 kHz or 88.2 kHz to 44.1 kHz.
Which is better 24-bit or 32-bit?
A 24-bit signal has a potential signal-to-noise ratio of 144dB. That’s greater than the total range of human hearing (140 dB). A 32-bit signal theoretically has a signal-to-noise ratio of 192 dB, which is way, way beyond the range of human hearing by a factor of about 300.
Is 44.1 KHz good enough?
For most music applications, 44.1 kHz is the best sample rate to go for. 48 kHz is common when creating music or other audio for video. Higher sample rates can have advantages for professional music and audio production work, but many professionals work at 44.1 kHz.
