Some tips: 1) Numeric elements (bytes, bytearrays, shorts, integers, longs) can be read directly from the stream. ie (4 byte Integer) = Read #Stream As Integer. Gambas can handle little endian/big endian issues. 2) Fixed length strings must be handled in a two stage process. First, the required string length number of bytes is read into a byte array. This byte array is then converted to a string. Sample code: Dim Bytes As New Byte[StringLength] Bytes.Read(Stream) FixedString = Bytes.ToString() Note: Bytes.ToString stops the string conversion at the first null or at the end of the array. Therfore, you don't have to worry about null-terminated strings. v2 tags are more complicated, particularly since the tags can be ascii, either kind of utf16, or utf8 encoding.

Some tips: 1) Numeric elements (bytes, bytearrays, shorts, integers, longs) can be read directly from the stream. ie (4 byte Integer) = Read #Stream As Integer. Gambas can handle little endian/big endian issues. 2) Fixed length strings must be handled in a two stage process. First, the required string length number of bytes is read into a byte array. This byte array is then converted to a string. Sample code: Dim Bytes As New Byte[StringLength] Bytes.Read(Stream) FixedString = Bytes.ToString() Note: Bytes.ToString stops the string conversion at the first null or at the end of the array. Therfore, you don't have to worry about null-terminated strings. v2 tags are more complicated, particularly since the tags can be ascii, either kind of utf16, or utf8 encoding.

I've attached an archive containing the code I use to read v1 and v2 MP3 tags and other MP3 info including bitrates (fixed and VBR), sampling rates and number of channels. v1 tags are pretty staightforward to read if you don't try to read the structure directly, but by each element of the structure at a time.
