Over die exe ben dit tegen gekomen.
A MIME attachment with the content type "application/octet-stream" is a binary file. Typically, it will be an application or a document
that must be opened in an application, such as a spreadsheet or word processor. If the attachment has a filename extension associated with it, you may be able to tell what kind of file it is. A .exe extension, for example, indicates it is a Windows or DOS program (executable), while a file ending in .doc is probably meant to be opened in Microsoft Word. In addition to the generic application/octet-stream content type, you may also encounter attachments that have different subtypes (e.g., application/postscript, application/x-macbinary, and application-msword). They are similar to application/octet-stream, but apply to specific kinds of files.
No matter what kind of file it is, an application/octet-stream attachment is rarely viewable in an email, Usenet, or web client. If you are using a text-based client, such as Pine, trn, or Lynx, save the attachment to your account, and then transfer it to your personal computer using SFTP. IU Webmail allows you to save attachments directly to your personal computer; see In IU Webmail, how do I use attachments? If you are using a workstation-based client, such as Thunderbird or Outlook, the application should be able to extract and download
the attachment automatically. After downloading an attachment through any of these methods, you must then open the attachment in the appropriate application to view its contents.
Over dat andere er zijn programma's (ik ben ze voor kort nog tegen gekomen) waarmee je ze op een enkele muziek toon precies er uit kan halen.
Omzetten naar mp3 of wav lijk me geen enkel probleem en als dat wel een probleem zou zijn dan neem je het geluids fragment op met een software recorder die dat weer opslaat als mp3 of wav.
Leuk school opdracht ,al is het wel even zoeken.
