Recommendations for digital recording Plan for preservation ...

  1. 1. Recommendations for digital recording
  2. 2. <ul><li>Plan for preservation of the original recording before the project starts </li></ul><ul><li>Plan for access to the recording on the web, etc before starting the project </li></ul><ul><li>Use the best recording equipment you can afford </li></ul><ul><li>Plan for eventual obsolescence of all media formats </li></ul>
  3. 3. <ul><li>Solid state: uses flash memory </li></ul><ul><li>Hard-disk based: records to an external or internal hard drive </li></ul><ul><li>CD recorders </li></ul><ul><li>Direct to computer: sends the signal to the computer via a firewire or usb connection </li></ul>
  4. 4. <ul><li>Compact Flash, SD, SDHC are usual memory types </li></ul><ul><li>Familiar – used in digital photography </li></ul><ul><li>Records at very high quality settings </li></ul><ul><li>Reuseable </li></ul><ul><li>Easy to transfer to PC or other device </li></ul><ul><li>Media cheap and getting cheaper </li></ul><ul><li>Fastest growing segment of the market </li></ul>
  5. 5. <ul><li>Larger capacity than flash memory recorders </li></ul><ul><li>Upload/transfer at a rapid rate </li></ul><ul><li>Supports very high quality recording </li></ul><ul><li>Drives getting less expensive </li></ul><ul><li>Recorders becoming more portable </li></ul><ul><li>Generally associated with high end recording </li></ul>
  6. 6. <ul><li>Inexpensive and accessible </li></ul><ul><li>Common now, but fading? </li></ul><ul><li>Limited to 80 minutes of recording </li></ul><ul><li>Quality options are limited </li></ul><ul><li>Larger recorders </li></ul>
  7. 7. <ul><li>Requires a computer and professional level audio interface </li></ul><ul><li>Large capacity – can record at high quality for long period of time </li></ul><ul><li>Sometimes have noise interference from computer fans, etc </li></ul><ul><li>Requires audio editing software </li></ul><ul><li>No need to upload until ready to backup files </li></ul>
  8. 8. <ul><li>For archival purposes, uncompressed is the best way to record. Compressed audio is best utilized for creating web deliverable files, not for recording the original interview. </li></ul><ul><li>Standard formats are .wav and .aiff </li></ul><ul><li>.wav is generally used by portable field recorders </li></ul><ul><li>.aiff is usually Apple format </li></ul>
  9. 9. <ul><li>Many low-end consumer recorders—ones designed for dictation and usually purchased at office supply stores— record in a proprietary compressed format that can only be accessed using a proprietary software package. Because format compatibility and interoperability are of the utmost importance from an archival perspective, these low-end consumer recorders are not recommended for recording oral histories </li></ul>
  10. 10. <ul><li>Use AC power if at all possible </li></ul><ul><li>Have battery backup available </li></ul><ul><li>Use a good external microphone: an inexpensive recorder with a good mic is better than an expensive recorder with a cheap mic </li></ul><ul><li>Record as uncompressed .wav files </li></ul><ul><li>Turn your cell phone off – can create interference </li></ul><ul><li>Purchase the best equipment you can </li></ul><ul><li>Always backup your recordings </li></ul>
