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.

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.
