• What is Pure Vinyl?

Pure Vinyl is a package of audio recording / editing / archiving applications designed from the ground up for making the highest possible quality transcriptions from vinyl recordings, and the highest possible quality playback of those transcriptions.

Pure Vinyl isn't just confined to being used for vinyl transcriptions.

- Any audio file (96 kHz or less) can be edited and split into individual tracks. For higher sample rates, Pure Vinyl includes an extremely high quality decimator to generate 44.1 kHz or 96 kHz output files. After generating the vinyl overview and track split images, audio files up to 192 kHz / 32 bit can be played (and can provide real-time RIAA equalization for raw, unequalized archive recordings).

- Pure Vinyl also provides a unique and fun "vinyl visualizer" feature. Pure Vinyl uses tracks from an iTunes playlist, generating an entertaining, animated display, while providing playback and track seek (drag the "tonearm") controls.

For detailed information, please visit http://www.virtual-vinyl.com. Additional documentation and tutorials will be available soon at that website. The Pure Vinyl User Guide.html file (open using Safari) contains information to help you get started.

• System Requirements

Mac OS X 10.4 ("Tiger") or later is required. Pure Vinyl will not launch on earlier versions of Mac OS X. A G4 or newer CPU is required. The Pure Vinyl applications are Universal binaries that will run on Macs with either Intel or PowerPC (G4 or G5) processors.

Dual 867 MHz or better CPU required for simultaneous recording at 192 kHz and downsampling to 44.1 kHz. System requirements are lighter at lower sample rates or without downsampling. Pure Vinyl Recorder is multithreaded for highest performance on multi-CPU or multi-core processors.

• Installing Pure Vinyl

Drag the Pure Vinyl folder to your Applications folder. (A copy of this Read Me file is already provided inside the Pure Vinyl folder.)

- If updating the entire Pure Vinyl suite, drag the Pure Vinyl folder to your Applications folder. When asked if you want to replace the folder, click Replace.

- If updating one of the component applications in the Pure Vinyl package (Pure Vinyl or Pure Vinyl Recorder), drag the application to the Pure Vinyl Folder.

Application updates may invoke the original launch message screen; however, your application preference settings will be preserved, as will your activation code (if one was purchased).

- Demo Version Limitations

Pure Vinyl Recorder: After 5 cumulative minutes of recording, or 12 cumulative minutes of listening (on a per-launch basis), whichever occurs first, the sound level will be ramped down by 10 dB, then back to normal, at approximately 1-minute intervals. When this behavior goes into effect, the message Demo Ramping Sound will appear in the Pure Vinyl Recorder window.

Pure Vinyl: When rendering tracks, the signal gain will ramp very slowly down and up by about 12 dB. Keep this in mind if you work through the Tutorial Example. The Decimator feature also will follow this behavior after 3 minutes (CPU time, not track time) of decimation. When this behavior goes into effect, the message Demo Ramping Sound will appear in the Pure Vinyl Decimator window.

- Purchasing an Activation Code

1. Open the Pure Vinyl Recorder application.
2. Select Preferences from the application menu.
3. Select the Registration tab in the Preferences panel, and follow the instructions there.
4. After the activation code information is entered, you will have to relaunch Pure Vinyl Recorder (and Pure Vinyl, if already running, in that order) to complete the verification of the activation code. The Purchase Activation Code button (and other items besides the entry boxes) in the Registration tab will be hidden after successful verification.

• Pure Vinyl iTunes Integration: "Vinyl Visualizer"

Pure Vinyl can create and "play" visual vinyl singles created from music files in your iTunes collection.

To use, just launch Pure Vinyl. The first launch will show a screen with instructions on how to activate this feature.

You can control the playback, track position, and step through your iTunes playlist. The audio in the tracks is used to create an animated "virtual vinyl" representation of the music. Pure Vinyl functions as a fun visualizer that harkens back to an earlier era.

The first time Pure Vinyl encounters a track, it will take several seconds (depending on the duration of the track) to obtain tag information and render the vinyl image. Pure Vinyl will cache the images, so the next time the track is encountered, there will be very little delay before playback.

The singles images are in TIFF format (to preserve image transparency) and occupy about 2.2 MB each. They are saved in artist folders created in Users/your username/Music/Pure Vinyl/Track Lists and Vinyl Images/. The caching of images can be disabled in the Vinyl Rendering tab of the Preferences panel; uncheck "Retain Images" to disable caching (and the image will be re-rendered each time the track is played). There also are other small files created in the same location, that work with information stored in Users/username/Music/Pure Vinyl/Pure Vinyl Music Catalog Singles.plist. Do not delete these files. However, if you decide to delete these files, you also must delete the Pure Vinyl Music Catalog Singles.plist file.

Note that the techniques used here for fetching tracks from iTunes may fail on non-Roman language scripted systems. In most cases, the iTunes interaction feature will automatically be disabled and not selectable. However, if you encounter problems, we would like to hear from you (pvsupport@channld.com). When responding, please keep in mind that this currently is a "free" feature that can be used without having to purchase an activation code.

One thing that will currently NOT work regarding the iTunes integration is if: (1) Fast User Switching is activated, (2) the iTunes music resides on a network volume, and (3) the volume is mounted in more than one logged in user account. Only the first user who mounted the remote volume will have the automated feature work. We know the cause of the problem, and are attempting to craft a reasonable solution.

• Troubleshooting

If you encounter any problems, the Pure Vinyl applications can be reset to their initial, pre- first launch states by deleting the application preferences files located in Users/your username/Library/Preferences. The files are called com.channld.PureVinylRecorder.plist and com.channld.PureVinyl.plist.

Album catalog information also is stored in several Pure Vinyl Music Catalog.plist files in the Users/your username/Pure Vinyl folder. Make a copy of (rename) these files and then delete the originals, if necessary, for troubleshooting.

- Improved performance of inverse RIAA equalization for playback
- Fixed inverse RIAA equalization file playback problem (176.4 and 192 kHz)
- Cleared state of decimator for successive decimation operations
- Corrected problem that caused sample rate query dialog to appear
- Better keeping track of manually added singles (would needlessly show the Album Info entry window)

1.1.1
- Decimation routines run about 20% faster
- Expanded documentation: Opening Audio Files, Recording, Rendering
- Changed 10 dB monitor volume pad option to 20 dB
- Fixed cosmetic problem with rendering dialog
