Thanks Michael for answer.

Here is the schema of recording:
1) At creation:
DataRec := TMemoryStream.Create;
2 ) In loop:
DataRec.WriteBuffer(InputBuffer, Length(InputBuffer)); // RAM used
increase at each loop
3) At end of recording:
function WriteWave(FileName: ansistring; aDataRec: TMemoryStream): word;
f := TFileStream.Create(FileName, fmCreate);
f.WriteBuffer(ID, 4); // add some stuff for wav header.
> ... buffer in which you had data
The buffer (InputBuffer) used to get the samples from input device is
re-filed at each loop.
The data of (InputBuffer) are added to the other buffer (DataRec) used for
WriteWave() (procedure at end of recording) in each loop.
Huh, maybe I did not understand your question.
Many thanks ;-)
