  1. What is DRM? You write "I don't know of any voice recorders that will save as uncompressed audio simply because the frequency spectrum for voice is well defined, and hence they would most likely use a codec specifically designed for compressing such an audio signal." Why would they not save it uncompressed if it will be a higher quality sound for somoene who needs to do editing to work with? Also, can you give me a name of a qaulity audio recorder that is not just for voice recording? How pricey is it? Is it worth to make this investment if I am recording hundreds of lectures? Or is recording in MP3 likely to give me excellent quality that I can uncompress when I do my editing?
  2. Hi! I am also interested in this subject. I work on editing lectures. Sometimes, I combine lectures that were said on different occassions, and it sounds funny because the voice range is going up and down. You mentioned that if somoene is seriously interested they can send you a message using the messanger service. Where is that? Thank you!
  3. Hi! I was wondering if anyone can recommend - What is the best qaulity audio recorder out there. I am currently using an Olympus Model # MS300, to tape lectures at a conference. It saves the audio lectures as WMA files. Are there any recorders that save the files in an uncompressed format? If not, what is preferable, if the recorder saves it as a WMA file, or an MP3. I want to make sure that the lecture is recorded in the best quality possible, so that editing will be easier. I am using an external microphone as well. Any recommendations on that? Thank you!

    OK! I was making myself crazy with that crying baby!!! What does it mean that the spectral subtraction method is slower but more accurate? Also, are there any other methods of noise reduction to try aside from the two I mentioned previously?

    Hi Nchto, You wrote "You can open the compressed mp3 file and edit it, but if you wish to save it for further editing then you should save it as a PCM encoded WAV file (uncompressed audio) using the highest settings available." I'm not sure I understand correctly. Shouldn't I do any editing only in PCM format. What do you mean when you write that I can edit it in mp3 format and only for further editing save as a PCM? And I'm still not clear about the audio files that I already worked on - that I wrote about previously I edited them in an uncompressed format, and then saved it as an mp3, and subsequently realized that it needs more editing, should I resave that mp3 file as a PCM file to do the edits, or once it was already compressed as an mp3, converting it back to a PCM will also reduce quality? Which way would be most ideal to do the editing on this mp3 file?
  6. Hi! Here are some additional technical questions I have while learning to navigate wavepad!!! If someone is taping audio lectures using an irivers digital recorder, are there any tips for recording that will ensure the highest quality sound. I will later be editing these audio lectures, and obviously I can’t make the edited version sound better than the original. This may sound like a funny question, but in which format do these digital recorders record the audio, is it in an uncompressed form, is there such a thing? Or it that an action you can do to the audio file (using a program) after it has been recorded in whatever format it records…. If I edited an audio file in an uncompressed format, and then saved it as an mp3, and subsequently realized that it needs more editing, should I resave that mp3 file as a PCM file to do the edits, or once it was already compressed as an mp3, converting it back to a PCM will also reduce quality? Which way would be most ideal to do the editing on this mp3 file? Is applying noise reduction considered an editing action. In other words, if I am planning to use the noise reduction feature, is it best to do it on a file that is uncompressed. Also, would you apply the noise reduction as the first action you would do on an audio file prior to any cutting of material, or would you do it after? Thank you in advance for responding to all of my queries.

    Removing Hiss

    I tried using the spectral subtraction method for noise reduction. (What does it mean that it is the slower but more accurate method? That it takes longer to apply???) And multiband gating as well. The problem is that there is a baby crying in the background that is crying as loud as the speaker is talking – is there any way to remove that sound? It didn’t work completely with either of these methods. Thanks again!!

    Thank you for your helpful response. I was just wondering if you could be more specific about the noise reduction features. Which one is best to use - and how to use it.

    Removing Hiss

    Hi! I just started using wavepad, and need some help!!! I'm working on an audio file (a lecturer is speaking) that has a constant hiss in the background. How do I remove it without making the audio sound wierd. Also, I am listening to an hour long lecture that requires a lot of cutting. What format is the best way to save it in, while I am doing all of my editing. Please be specific about the HZ and bit.... Does each editing action reduce the quality of the audio file? Does each time I press save after a specific cut does it reduce the quality of the audio file? Finally, I would like to eventually post these short audio files on a website. How should I compress it so that it will be easy to listen to, without a noticeable change in quality. Please be specific about the HZ and bit stuff..... Thank you!!!!
