2 Re lec ions
Robe Ashley (1930-2014) has had a signi ican impac on my musical aes he ics since I became
amilia in 1995 wi h his ope a Imp o emen : Don Lea es Linda. He speaks like people I know
(Midwes USA), assembles laye s o ex and sub ex wonde ully, and has a unique s yle ha I
enjoy. So, I wonde ed, how migh he in e p e he ToS o Udio? Then I wonde ed: How well can
Cha GPT and Udio mimic Ashley’s inimi able oice? This audio- isual wo k answe s ha
ques ion. I ind he ou pu o Cha GPT o p o ide a su p isingly good imi a ion o Ashley. I can
ecognize in he gene a ed ex hings I would expec him o say. The na a ion gene a ed by Udio
sounds like him speaking in an in e iew, bu is missing a ew sub le aspec s o his cha ac e is ic
“d awl”. The music gene a ed by Udio is by and la ge qui e di e en om his own, which is
essen ially slowly un olding se ial-composed minimalism accompanied by ampli ied oices.
Pe haps some po ions o he gene a ed music a e eminiscen o In Sa a, Mencken, Ch is and
Bee ho en The e We e Men and Women—bu ha music was ac ually c ea ed by Paul DeMa inis.
None heless, my goal o his wo k was no o c ea e music ha sounds like i was made by Ashley.
I consciously a oided eplica ing aspec s o his s yle, such as a se ial app oach o composi ion, a
cho us, call and esponse, and his idiosync a ic deli e y o ex . (I do use d ones, howe e .)
(None o he ex o ideas in his documen we e c ea ed by o wi h an LLM.)
