Pick any of the ISD chips with an 8kHz sampling rates. These are alwasy
the lowest recording time versions in each family. For example the 2560
has a sampling rate of 8kHz and a filter passband of 3.4kHz. This should
be adequate. Quality is very good. The ISD1416 has similar
characteristics, but less storage capacity (16 secs). Again this should
be plenty. If you want 2560's I've got around 90 hanging around in DIP
and SOIC, you're welcome to a couple.
