My turntable was fed to an ARTcessories phono pre-amp which in turn fed an Edirol UA-1EX external USB soundcard and this into a USB port on my PC (I did start out with a cheapy USB turntable but the sound quality was rubbish). The objectives were to produce good quality compressed audio on my iPod but also to provide high quality uncompressed files to play on my hi-fi rig (old kit but still comparatively high end QUAD 33/303 feeding QUAD ESL-57 electrostaticspeakers) My first major use of Audacity was to convert my vinyl collectionn (and subsequently my wife’s vinyl collection). What is unarguable is that 96000 Hz takes more than twice the disk space of 44100 Hz, and so there is increased risk of recording dropouts if the computer is slow. Have a read of that and make your own mind up. Some may argue that at 96000 Hz you will benefit from analogue anti-aliasing, but argues that down and generally argues that extreme sample rates are counter-productive. Otherwise you will get lossy downconversion to the track rate with every effect. If you are running effects that change the sample amplitudes, you should set Default Sample Format to 32-bit float because Audacity processes internally in 32-bit float. If “bit perfection” is your requirement, and you are not running effects that change the sample amplitudes, you could set Default Sample Format to 16-bit, set project rate to 44100 Hz, and turn dither off in Quality Preferences (dither should not be applied when exporting to a 16-bit audio file from a 16-bit project, but it’s applied due to a bug). Otherwise you are recording at 16-bit which is being converted to 24-bit resolution if Default Sample Format is 24-bit or to 32-bit float if Default Sample Format is 32-bit float. You aren’t recording at 24-bit unless you have a 24-bit interface and you’re choosing Windows WASAPI host. Would this result in a higher audio quality as opposed to recording natively at 16/44? Would I bet better off (quality wise) recording at say 24/32 bit depth - 96khz sample rate, and then downsampling to my desired 16/44. I’m not sure why you had trouble with FLAC. Plus, dither is low-level noise so you’re just adding to the existing vinyl noise. (Some downsampling algorithms “measure” better than others, SoX has a reputation for being one of the best, but I’ve never heard any difference, no matter what software I was using.)ĭithering is normally recommended whenever you downsample, but you shouldn’t hear any difference unless you dowmsample to 8 bits. Just change the sample rate (lower left corner of the Audacity window) and then set the bit depth when you export. Is there a recommended way of downsampling? Records are worse than human hearing and you can’t make a vinyl record sound like a CD. Think about it… You can easily hear vinyl defects, especially noise but sometimes distortion and frequency response variations, but you can’t hear any limitations of 16/44… CDs are better than human hearing and you can make a CD or digital file that sounds like vinyl. But, it’s not necessary with analog vinyl. There’s no harm in using 24/96 other than large files. My sound card is capable of recording at 24/96. I’d like to end up with a 16/44 rip and a 24/96 rip. Soundcards (ADCs & DACs) are integer devices but the software will make the conversion. By default, Audacity works in floating-point internally and you should leave it that way.
