I recorded some of my best collection on songs from cassettes to wav using the latest edition of Polderbits Sound Recorder and Editor and a Sony Walkman for line input. I got amazing results using Polderbits. Now one problem troubles me is that at the beginning of the songs and at the end there is terrible hiss sounds , I tried using Wave Corrector 3 but its too teidious as it is not done in real time. Can anybody suggest a good pair of plugins where i can use with N-track or Goldwave to remove the hiss or any standalone sound App.
Secondly i want to convert all my files to Ogg and store them. But previously i have a collection of mp3s i wanna convert to ogg. But i heard it is not a good idea to use lossy compression from converting from one to another. So converting to Wav and then to Ogg will it solve my problem....and yes without losing any quality.
Lossless comressors are too bulky to store audio for future reference.
Kindly advise !

1) Sonic Foundry Noise Reduction is a good plugin to remove noise/tape hiss. Also notice that using a walkman is not a good input source. You might want to see if you can find a deck of higher quality

2) The process of going from one format to another is called transcoding. You cannot go from one lossy format to another without losing quality. It does not matter if you convert to wav in between. That wav will only have the quality of the mp3, it cannot magically restore what has been lost in encoding to mp3. I suggest you search the forums for "transcoding". I'm sure you will find plenty of interesting material. There is even a informal transcoding listening test. It is best to keep the the mp3's you have and just from now on use ogg if it so suits you.
