So the question is: is it possible to add to Raw ability to load up Raw sound files?
I have now slated raw support for Rave version 1.6, to be released in February or March. There will be a smaller update in between coming out in January.
Version 1.5 is up on os4depot.net. In this release you'll find:
- A new function in the Process menu: "Reverse". - A new function in the Edit menu: "Paste at". - A new function in the Edit menu: "Insert Silence". - A user-defined amount of silence can also be inserted when creating a new project. - Updated documentation.

I've been playing with this new "Reverse" feature trying to find satanic verses when playing songs backwards. Haven't found any yet.
I did run into one issue where the bitrate was changed to 32k when I saved the file.
I loaded a song with a variable bitrate. I then reversed the waveform. At this point the save button is activated in the toolbar. I clicked it and the waveform was saved over the original without warning, which suprised me a bit. On playback I noticed that the quality had been degraded a lot. Checking the bitrate I saw that it had been changed to 32k.
Note: This also occurs with other feature like fade, etc.
I also noticed that a 192k fixed bitrate song was reduced to 125k after saving. Would it be possible to save at the original bitrate by default?

This is normal and expected behaviour for the Save function. You don't want a "File has been modified!" warning requester here because it's understood - the Save function only becomes available when the file has been modified. But I'm thinking about bringing up the Save As file requester in this situation for lossy formats, so that the user can configure them before saving.

The problem is that libsndfile doesn't support saving at a user-specified bitrate. You can only set Encoding Quality for variable bitrates, or choose from a selection of fixed bitrates as provided by the library. From what you've described, I think the problem is that my code invokes Save using the default encoding options, instead of trying to configure them closer to the original bitrate. I'll have a look - until then, please use Save As
No problem. I'm enjoying using Rave. The insert silence feature is very useful.
Perhaps a Save as button in the toolbar would be good as well. I most likely won't want to save at the default bitrate.
If possible, a way for the user to select a specific fixed bitrate would be good, or maybe some documentation of what bitrate or range of bitrates the different quality settings will use.

I agree, it's on my to-do list.

It surely would, but unfortunately, the I/O library Rave uses doesn't support that It only allows setting an abstract "compression level" as a value between 0 and 1.0, which the library internally maps to a bitrate value. So I don't have much control over that. Even if I find out that, for example, compression level 6.0 corresponds to 128kpbs for a 44.1kHz file, it will be a different bitrate for a lower-frequency file. So I can't just offer a selector in Rave with pre-defined bitrate values to choose from.
The Save function now (i.e. in the upcoming version 1.6) works as follows:
- If the project was loaded from a file format that is also supported for saving (such as WAV or AIFF), the Save function will save the file immediately. As I said, this is the standard and expected behaviour. An "Always confirm save" prefs option may be introduced at a later point to help prevent accidental overwrites. - If the project was loaded from a file format that is not supported for saving (such as VOX or AU), the function will bring up the Save As requester so that the user can choose and configure the target format. - If the project was loaded from a compressed file format such as MP3 or FLAC, the Save function will first bring up a configuration window for the respective format so that the user can configure the compression parameters. The window also has a Cancel button, so the saving can be cancelled at this point if needed.
A lot of improvement since the current public version I think
@ktadd Thanks for reading! Oh by the way, your Save As toolbar button is implemented in the new version
Finally got a chance to download and try out the new version. Loving all the supported formats and the Save As with the ability to Configure the setting! Small donation on the way. Bigger donation to come once recording gets implemented. That would really round out the applicatoin nicely. Keep up the great work! Thanks!
