<p class="MsoNormal">I am using an old cassette player lineout fed to a Zoom h6 Essential.<o:p></o:p></p>
<p class="MsoNormal">The tapes, as I said, are old recordings of lectures, interviews, and speeches. Most of the tapes are home-made. Also, there are a few commercially-produced.

<p class="MsoNormal">I can do basic de-essing (some of the tapes really need it).<o:p></o:p></p>
<p class="MsoNormal">I don’t have a lot of experience eliminating tape hiss with filters, so any suggestions are very welcome.<o:p></o:p></p>

<p class="MsoNormal"><span style="font-family:"Aptos",sans-serif">I have had some experience with digitizing old recordings, although I don’t know that I have gotten into it to the degree that Ty has.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Aptos",sans-serif"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Aptos",sans-serif">It would be helpful to know what equipment you are using and if you already have any audio software such as Audacity, Gold Wave or something similar. To play the cassettes, are you using a cassette
deck or are you using a cassette player?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Aptos",sans-serif"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Aptos",sans-serif">There are a number of options for removing noise, but frankly, it is very easy to introduce other problems when doing that. As Ty has already stated, there is a lot you can do through equalization,
and hum can largely be removed with a notch filter. Equalization can be applied with less risk of introducing additional problems. Most audio editing programs contain some kind of equalizer.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Aptos",sans-serif"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Aptos",sans-serif">Let me know more about your equipment and we could discuss this offline if you like.<o:p></o:p></span></p>

<p class="MsoNormal">I’m in the process of digitizing a number of old cassette tapes of lectures, interviews, etc.These are *old tapes, and most of the audio so far is muddy or sloppy on the sibilants – tape degradation, I’m sure.<o:p></o:p></p>

<p class="MsoNormal">A quick Google search has found apps that are especially for cleaning up podcast voice recording.<o:p></o:p></p>
