Need circuit to create an analog delay of 30ms

[watersky]

hello everyone,I have a question about delay. I require a delay of 30ms or above, which is an analog delay. It is said an analog signal is as an input of block, and it will appear in the output of this block after 30ms. Input and output signal, such as music signal, must be a consecutive signal. the delay time of allpass filter is so litter. I want to know what is circuit?

Re: analog delay

think about implementing an all-pass-filter ...
