OK, I have an on-going dispute with a fellow production director from another radio station. He wants everything I send him produced at a rate of 41100; generally I keep things around 32-5 or 6. He claims that unless the rate is 41-1 the ads are not airable. I say the 32-5 is plenty. What say you?

Hey there. Well, 44100 (i think this is what you meant) is the CD standard sample rate. 32500 is a bit more 'lo-fi' and is actually the rate that some DAT machines will record at in 'long play' mode. The difference is maximum frequency. At 44100, you have a frequency response up to 22Khz; at 32500, your frequency is limited to just above 16Khz. Now, for vocals over radio, 32.5 is probably just fine...But add compression, limiting, and over-all signal distortion from broadcast and that 16k bandwidth probably begins to dwindle down to more like 13-14k.

Hope that helps.

What format are you sending your spots? We receive a lot of MP3s via the internet and they sound fine (128kbs). However, we always produce everything 44100 as it's easier (and cheaper) to burn a dub on a CD rather than a cassette/reel for a client/station. Just my 2 cents.

Chiefgunner,

Sending audio in the 44.1K sample rate is the standard for radio. Having dealt with other stations, ad agencies, and independant producers, all of them send and request spot ads at 44.1K.

From a production stand point it makes sense. How many times have you set up the Reel-to-Reel for a 15ips playback only to find out that the producer dubbed it at 7.5ips? Or vise-verse? Also, the dynamic range is much greater and less suseptable to degridation. Why monkey with speed diffrences in this new digital age? You need to also start requesting and sending at 44.1.
