what does it mean if your cassette deck playback and recording sounds warbly?


what does it mean if your cassette deck playback and recording sounds warbly? I just got a brand new Tascam CD-A580, and my recordings and playback sounds shaky or warbly.

@leemurray2007,

I only reported your posts after I felt your tone got abuseive towards me.  This was only the second time in13 years on the forums I have reported a post.  I don't like doing that, really don't, but I was afraid it was going to escalate further.

I agree we both have to show restraint and I hope this puts the arguement to rest.  I guess we can call it a reboot.  I feel we got off on the wrong foot and hope going forward we can be friends or at least civil to one another.  I am glad you posted as this has bothered me a lot.  Take care.
Thanks for being sincere with your response. I was looking at my past posts and saw that I did have a very negative tone.


Right now is no time to get into an argument with someone, especially someone you don't know.

I respect you and your history on this platform.

Again, my apologies.

Ottens, who died on Saturday, had little patience with the renewed popularity of the cassette tape – or even vinyl.

“Nothing can match the sound of the CD,” he had told the Dutch newspaper NRC Handelsblad. “It is absolutely noise and rumble-free. That never worked with tape … I have made a lot of record players and I know that the distortion with vinyl is much higher. I think people mainly hear what they want to hear.”
Think he naild it.
