Can anyone recommend a line-in recorder that has the following features:

• Start and stop recording at a set time
  
• Auto file splitting after the windows 2GB limit is reached.

On that last point, I was recording off the radio overnight with Exact Audio Copy. When I woke up, EAC had froze and the WAV file was exactly 2GB. I copied and pasted the WAV file to a new folder and terminated EAC.

The WAV file (both of them) now seems to be corrupt somehow. Cool Edit, Media Player, Winamp and Lame all give errors when I try to open it, and when I try the "Process Wav" option in EAC, it says that the input wave file should be at least 2 samples long.

Is there any WAV Cutter/Fixer that can fix my WAV file?

You might be able to load the file into CoolEdit in "raw" PCM mode. Then, you would manually delete the header from the beginning (to avoid a "click") and save it back as a regular wav. This assumes that CoolEdit can handle >2GB files, which I don't know.

Good luck...

No, this doesn't work. I was wrong when I said Cool Edit gave an error message, it actually just it opens it as a blank waveform with zero length.

Is there a general file utility that can cut any file into X pieces?

Don't know whether this one would do you any good or not; I've never tried it, but I made a note of the link when I learned of it. Messer (Memo Session Sound Recorder) does scheduled WAV recording - it also claims to support on-the-fly MP3 encoding via Lame_enc.dll - and the last updated build (0.98) added this feature: "new tool: "Advanced stop" (under Recording Monitor->Options menu), allowing (even for already started manual recording) to stop manual session after specified time or when silence is detected. Also allows to automatically split recording to multiple files, basing on silence detection." Assuming your program includes some occasional silence, and assuming the "manual" features also work during scheduled recording (?), this might do the trick. Good luck, if it does.

Try this:
Loop Recorder

would someone be able to post some good presets for lame mp3 encoding with messer? also since i want to use lame 3.90.2 i am using the lame3.90.2-modified_dll-ICL compile, does anyone know of any other?

No it doesn't work.

One might schedule a few sessions starting immediately one after another, but I can't guarantee that there won't be missing samples in "transitions" between files (Messer closes and reopens recording device...).

A the time Messer was written and actively developed the DLL interface was giving out only a few basic options and there was no "alt-presets" enabled version yet...

You can only set "q", "min" and "max" bitrate for VBR encoding and this really makes direct-to-mp3 recording with Messer not recommended from quality point of view.

If it need not be lossless try TotalRecorder.

Regarding your corrupt file, check its properties and see if it reads 0 bytes.

If it does you are going to need some kind of data recovery prog to retrieve the data. If you havn't been using your system too much, you might be able to restore your file.

I get bizarre stuff like this on my win98se when BSOD problems crop up in the middle of processing a large file. The file is still there but is good for shit because it has no data.

I use messer for the stuff you are trying but you could look at this too.

It allows you to encode with alot more command line control than messer but it may not have a timer. There have been a couple of new releases since I have used it, and the developer had said he was going to add a timer at some point.

Does the idea of compressing directly to high bitrate mp3 present a problem for you? High bitrate CBR is really easy to edit and would increase your possible recording time alot.

Have a look at the free versiion of Audiograbber - I have used this for a couple of years to record from the radio via line-in. It will encode on the fly to MP3 and Ogg Vorbis via included DLLs - other formats via external codecs.
It has very good scheduling facilities and button-click access to Windows line-in level meter.

Using Lame 3.92 ABR160 I get filesizes of ~70MB/hour. My cpu is not fast enough to use alt-presets in real time but for FM radio ABR160 is probably good enough. If you want to use a lowpass filter you need to use Lame as an external codec.

I often record long sessions of the Irish LyricFM which in UK I can receive via Sky D-Sat.

For editing I use mp3directcut.

I'm using Waverec (www.waverec.de). You can schedule recordings and let them be split by a given interval. Problem could be that the program (and web-site) are german. An english version is planned.
